which muscle below could also be called the ‘pouting’ muscle?

Phenotypes are essentially the physical characteristics that an organism possesses that make it more likely than not that it would thrive in a given environment.

The following assertions are accurate:

1. Survival is a race that all species must win.

3. Some species possess traits that enable them to outcompete rivals in their environment.

5. Natural selection is still in action today.

6. Over the course of multiple generations, phenotypes that are present in a species' most successful individuals grow more common.

The complete question is Check all statements below that are true. All organisms must compete for survival. When organisms struggle to survive, they usually mutate to increase chances of reproduction. Some organisms have phenotypes that make them better competitors than others in their environment. Animals undergo natural selection, but plants and other organisms generally do not. Natural selection continues to occur even today. Phenotypes found in the most successful members of a species become the most prevalent after several generations. A decrease in food availability will increase the variation in a population.

Answer: Two electrons and a hydrogen ion

Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.

The ingredients needed to transform NADP+ to NADPH are an electron and a hydrogen ion.

Nicotinamide adenine dinucleotide phosphate ion (NADP+) is an energy carrying ion which transfers high energy electrons from chlorophyll to other molecules during photosynthesis.

Photosynthesis is defined as the process by which green plants are able to manufacture their own food.

In the light stage of photosynthesis, the electron and hydrogen atom released during photolysis of water is picked up by the energy carrying ion NADP+.

This is then converted to NADPH, that is Nicotinamide Adenine Dinucleotide Phosphate Hydrogen.

The biggest pressure drop in circulation occurs in the arterioles, which are small blood vessels that lead to capillaries.

These vessels have a small diameter and high resistance, causing the blood pressure to decrease significantly as it passes through them. This pressure drop is necessary to allow for the exchange of nutrients and waste products between the blood and tissues in the capillaries.

Arterioles have a smaller diameter than arteries and are capable of constricting and dilating to regulate blood flow to different organs and tissues in the body. This ability to regulate blood flow is important for maintaining blood pressure and ensuring that oxygen and nutrients are delivered to the tissues where they are needed.

However, the narrowing of the arterioles leads to increased resistance to blood flow, causing a drop in pressure.

This drop in pressure of circulation is necessary for blood to flow into the capillaries, where exchange of oxygen, nutrients, and waste products occurs between the blood and the tissues.

After replication there are a total of 46 chromosomes, with 92 individual chromatids, in each cell

In DNA replication, two DNA double helices are synthesized from one DNA double helix molecule when it unwinds and complementary nucleotides are added to the exposed unpaired bases.

A double-stranded DNA molecule is duplicated to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

The fundamental mechanism of DNA replication is similar across all species, making it a crucial operation.

Prokaryotic cells' cytoplasm and eukaryotic cells' nuclei are where DNA replication takes place. The fundamental steps of DNA replication are the same wherever it takes place. DNA replication is made simple by the DNA structure. The double helix has two opposing (anti-parallel) directions running through it.

Influenza viruses and others continually change over time, usually by mutation. This change enables the virus to evade the immune system of its host so that people are susceptible to influenza virus infection throughout their lives. Bacteria mutate in the same way and can also become resistant if overtreated with antibiotics.

Alleles are often described as being either dominant or recessive. The characteristic of recessive alleles that usually makes them 'recessive' is that the effects of the recessive allele can only be observed when two copies of it are present in an individual.

A recessive allele refers to a genetic trait that only expresses itself when there is no dominant allele present. When both alleles are recessive, the individual will show the trait associated with the recessive allele.

The dominant allele is represented by a capital letter (e.g., B), whereas the recessive allele is represented by a lowercase letter (e.g., b). The genotype of a dominant trait is indicated by two capital letters (BB), whereas the genotype of a recessive trait is indicated by two lowercase letters (bb).A dominant allele only needs one copy to be expressed, while a recessive allele needs two copies. An individual can only express a recessive trait if both copies of the gene are the recessive form. If an individual has one dominant and one recessive allele, they will show the dominant trait, which is why recessive alleles are often hidden or masked by the presence of a dominant allele.

Plants are multicellular eukaryotes.

The kingdom Plantae includes organisms that range in size from tiny mosses to giant trees. Despite this enormous variation, all plants are multicellular and eukaryotic (i.e., each cell possesses a membrane-bound nucleus that contains the chromosomes).

They generally possess pigments (chlorophylls a and b and carotenoids), which play a central role in converting the energy of sunlight into chemical energy by means of photosynthesis.

Most plants, therefore, are independent in their nutritional needs (autotrophic) and store their excess food in the form of macromolecules of starch. The relatively few plants that are not autotrophic have lost pigments and are dependent on other organisms for nutrients.

For a particular behavior to be considered an evolutionary advantage for a primate, it must provide a selective advantage that increases the primate's chances of survival and reproduction.

This means that the behavior must have a beneficial effect on the primate's ability to obtain food, avoid predators, find mates, or reproduce successfully.

Examples of evolutionary advantages in primates include social behaviors such as cooperation, communication, and altruism, which can enhance the survival and reproductive success of individuals within a group.

Ultimately, any behavior or trait that increases an individual primate's fitness (i.e., its ability to produce offspring that survive and reproduce) is considered an evolutionary advantage and is more likely to be passed on to future generations.

D) Antbiotics kill damaging bacteria by rupturing cell walls.

Explanation:

Antibiotics are drugs that kill bacteria or slow their growth. They function in various ways, but one common mechanism is by interfering with the construction of the bacterial cell wall, causing the bacterium to burst and die. Importantly, antibiotics are effective against bacteria, but they do not work against viral infections because viruses do not have cell walls.

The other options are not accurate:

A) Antibiotics do not attack all bacteria cell membranes. They selectively target specific types of bacteria, and some bacteria are naturally resistant or can become resistant to certain antibiotics.

B) Antibiotics are not effective against viruses. Viruses lack the structures that antibiotics target, such as cell walls.

C) Antibiotics do not protect the membranes of bacterial pathogens. Their purpose is to kill or inhibit the growth of these pathogens, not to protect them.

Answer:

Adhesion and surface tension

Explanation:

Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.

Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.

Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.

The twisting of the parental DNA strand around each other ahead of a replication fork is called DNA supercoiling.

Supercoiling is a natural process that occurs during DNA replication and transcription. As the DNA strands unwind to allow for the synthesis of new strands, the region ahead of the replication fork becomes overwound. To relieve this strain, the DNA molecules twist around each other in a coiled fashion. This supercoiling helps to maintain the integrity and stability of the DNA structure during replication and ensures the proper functioning of enzymes involved in DNA replication and transcription.

Hereditary spherocytosis results in normocytic, normochromic anemia in the peripheral smear because of the increased destruction of the red blood cells (RBCs) that are spherical rather than the normal biconcave shape.

Hereditary spherocytosis (HS) is an inherited disorder of the RBCs, which is caused by mutations in genes encoding proteins of the RBC membrane and cytoskeleton. The membrane and cytoskeleton protein deficiencies result in a decrease in the surface-to-volume ratio of the RBCs, leading to their sphere-shaped morphology. Additionally, this sphere-shaped morphology renders the cells more vulnerable to shear stress, decreasing their flexibility and making them less deformable than normal RBCs.

Consequently, HS is associated with splenomegaly, hemolytic anemia, and hyperbilirubinemia, which can lead to bilirubin gallstones and neonatal jaundice. In HS, the sphere-shaped RBCs are not as flexible as the normal biconcave-shaped RBCs. Thus, they become trapped in the smaller blood vessels of the spleen and destroyed, leading to hemolytic anemia. The removal of these sphere-shaped RBCs results in the formation of reticulocytosis, the premature release of immature RBCs, which leads to normocytic, normochromic anemia in the peripheral smear.

In conclusion, HS is an inherited disorder of the RBCs, caused by mutations in genes encoding proteins of the RBC membrane and cytoskeleton. The sphere-shaped RBCs are not as flexible as normal RBCs, and they become trapped in the smaller blood vessels of the spleen and destroyed, leading to hemolytic anemia.
