HELP!! I WILL MARK BRANLIEDT!! HERES A PIC ITS ABOUT NATURAL AND SELECTIVE BREEDING:)
Answers
Answer:
Natural Selection
- The process happens due to environmental activity
- It takes a relatively long period of time.
- Excessive warmer temperatures in a region have caused rabbits with longer fur to slowly disappear.
Selective Breeding
- Organisms do not choose to thrive but are selected because they are best adapted to the environment.
- A Labradoodle is created by scientists to be hypoallergenic but still look like a Labrador.
- It takes place over a relatively short period of time.
- Humans have a decision in the outcome of the offspring.
- Apples have gotten much larger over the last 30 years due to customer demand
Explanation:
From the above, I have been able to place them in their respective categories.
Natural selection simply has to do with nature. It is a process in nature that leads to the better adaptation of organisms to survive and reproduce in their environment. This type has to do with the natural environment. As nature plays out, it can take longer time and the environment can affect survival rate. Natural selection can lead to speciation.
Selective breeding can also be referred to as artificial selection. This process has to do with the input of man in developing new organisms that possess desirable characteristics and that can adapt to a specific environment. In other words, humans control and decide the outcome of the species that are reproduced. Such breeding process take relatively short time.

all of the following mechanisms are used to regulate protein production except group of answer choices dna replication. splicing the breakdown of mrna. protein activation.
Answers
All of the given mechanisms, including DNA replication, splicing, and protein activation, are involved in regulating protein production except for the breakdown of mRNA.
Protein production is a highly regulated process involving multiple mechanisms. DNA replication is not directly involved in regulating protein production but is responsible for the replication and transmission of genetic information from one generation to the next. It is not directly related to the regulation of protein synthesis.
On the other hand, splicing plays a crucial role in gene expression regulation. It is the process by which introns (non-coding regions) are removed from pre-mRNA molecules, and exons (coding regions) are joined together to form mature mRNA. This splicing process influences the types and amounts of proteins produced by alternative splicing and regulation of gene expression.
Protein activation refers to the post-translational modifications that occur after protein synthesis to activate or deactivate proteins. These modifications include phosphorylation, glycosylation, acetylation, and others, which can alter the protein's structure and function.
The breakdown of mRNA, also known as mRNA degradation, is involved in the regulation of protein production. It is a process by which mRNA molecules are degraded and removed from the cell, controlling the abundance and availability of mRNA for translation into proteins.
In summary, all the given mechanisms, except the breakdown of mRNA, are involved in regulating protein production. DNA replication is not directly involved in protein regulation, while splicing and protein activation play crucial roles, and mRNA degradation influences the availability of mRNA for protein synthesis.

Answers
Answer:
Its b trust me I did researched it a bunch looked through many pages and I found it Please give brainliess
Explanation:
The water vapor that forms ice crystals that join into flakes is not how snow forms; it is how rain forms. Hence, option D is correct.
How does snow form?Little ice crystals in clouds bond with one another to make snowflakes. Crystals will eventually get so densely packed that they are weighty enough to tumble to the earth. Snowflakes will melt at their edges and join together to form large flakes when they fall through damp air that is slightly warmer than 0 °C.
For clouds and snow to form, there must be adequate moisture in the atmosphere. Snow cannot form if there is insufficient moisture. The atmosphere must continuously add moisture to the clouds in order for snow to continue to form and fall to the ground during heavier precipitation. Hence, option D is correct.

The magma rises from Earth’s crust, pushing the North American plate and the Eurasian plate away from each other at the Mid-Atlantic Ridge, due to the movement of the plates, the Atlantic Ocean continuously becomes wider.
What are Tectonic Plates?Plate tectonics is the predominantly accepted scientific theory that states that the Earth's lithosphere is composed of several large tectonic plates which have been slowly moving since about 3.4 billion years ago.
When these plates move apart, magma rises to the surface a dozen kilometers below the ocean floor which form a new ocean floor. Large-scale volcanic events create large structures that over time form very ridges, plateaus like Azores, islands and seamounts.
Mountains arise where plates try and force together, or converge, as well as continents shift and oceans form where plates move apart, or diverge.
Thus, the magma rises from Earth’s crust, pushing the North American plate and the Eurasian plate away from each other at the Mid-Atlantic Ridge, due to the movement of the plates, the Atlantic Ocean continuously becomes wider.

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answers
Answer:
Through meiosis
Please find the description below
Explanation:
Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.
The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.
Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).
a man with type b blood marries a woman with type a blood. they have the first child with blood type o. what are the genotypes of the father (first) and the mother (second)?
Answers
For blood group: the father could have either BB or Bo genotype, and the mother could have either AA or Ai genotype. The child's ii genotype could have come from either parent having two i alleles or from one parent having an i allele and the other having a B allele.
The first child has blood type O, which indicates that they have the ii genotype based on the information provided. As a result, both parents must possess the I gene. One parent must be an I allele carrier. The father must have either the BB or Bo genotype because he has blood type B. Given that the mother has blood type A, the genotype must be either AA or Ai.
As a result, either BB or Bo might be the father's (first) genotype and either AA or Ai may be the mother's (second) genotype. The parent(s) with two I alleles could have been the child's parents, or one parent could have an I allele and the other a B allele.

Choose the types of alternative splicing patterns with the correct description of how they lead to the production of different protein isoforms. Select the three correct statements.
a)Alternative splice sites within an exon−different versions of an exon exist that allow for the presence of different domains in the protein.
b)Mutually exclusive exons−certain sequences are either included or excluded, which allows generation of proteins with different sequences.
c)Cassette exons−whole exons are excluded from the mature message, resulting in a protein that is missing certain sequences (perhaps an entire protein domain).
d)Alternative promoters−produce messages with different 5′ exons and proteins with different N-terminal ends.
e)Intron retention−introns are included in the mature mRNAs, which can be used only to produce novel isoforms of the protein.
f)Alternative polyadenylation−produces messages with different 3′ coding sequences as well as different 3′ untranslated regions, which can be important in regulatory events.
Answers
Alternative splicing patterns refer to the various ways in which exons and introns are combined to create different protein isoforms from a single gene. There are several types of alternative splicing patterns, but only three are correct in relation to how they lead to the production of different protein isoforms. These include:
a) Alternative splice sites within an exon: This type of alternative splicing pattern involves different versions of an exon that exist, allowing for the presence of different domains in the protein.
b) Mutually exclusive exons: In this pattern, certain sequences are either included or excluded, which allows the generation of proteins with different sequences.
c) Cassette exons: This pattern involves whole exons that are excluded from the mature message, resulting in a protein that is missing certain sequences (perhaps an entire protein domain).
By utilizing these alternative splicing patterns, genes can produce a wide range of protein isoforms with varying functions.
Your answer: The three correct statements about alternative splicing patterns that lead to the production of different protein isoforms are:
b) Mutually exclusive exons - Certain sequences are either included or excluded, which allows the generation of proteins with different sequences.
c) Cassette exons - Whole exons are excluded from the mature message, resulting in a protein that is missing certain sequences (perhaps an entire protein domain).

Chemiosmosis is involved in the generation of adenosine triphosphate (ATP), the primary chemical used by the cell for energy.
What do you mean by chemiosmosis?Chemiosmosis is the passage of ions down an electrochemical gradient over a semipermeable membrane bound structure. The generation of adenosine triphosphate (ATP) by the transport of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis is a good example. When ions flow through a channel, they generate potential energy, which can be used to power chemical reactions (red). Hydrogen ions, or protons, will diffuse from a high proton concentration zone to a low proton concentration region, and an electrochemical concentration gradient of protons across a membrane can be used to generate ATP. This process is similar to osmosis, the passage of water through a selective membrane, which is why it is named "chemiosmosis".

Semen is made up of a mixture of secretions from all of the following except? a) prostate gland b) bulbourethral glands c) testes d) seminal vesicles
Answers
Bulbourethral gland is not part of the secretions that made up the semen.
At the start of the internal section of the male reproductive organ, beneath the prostate gland, is the bulgurethral gland, also known as Cowper's gland. The bulbourethral glands have ducts that drain into the urethra, the tube through which both urine and semen enter. One of the tasks of the gland is to add fluid to semen during the process of ejaculation. They are made up of a network of tiny tubes, or tubules, and between the tubules are sac-like structures made of elastic and muscular fibers that provide the glands their structural support. Mucus, a viscous protein complex, is contained in droplets within the cells of the tubules and sacs. The clear, viscous fluid secreted by these glands serves as a lubricant, a flushing agent that cleans the urethra before to the ejaculation of the semen, and it may also aid to make the semen less watery and offer a proper living habitat for the sperm. The bulbourethral gland serves as a support system for the semen, as seen by the functions listed above.

1 is false and 2 is true because recessive alleles x recessive alleles = reccessive alleles, and since yellow is recessive, and you have no green birds, there is no possibility of having green birds without at least one green bird parent.
