why is it a good idea to plant only native species in your garden
Answers
Answer:
Native plants do not require fertilizers and require fewer pesticides than lawns. Native plants require less water than lawns and help prevent erosion. The deep root systems of many native Midwestern plants increase the soil's capacity to store water.
Explanation:
plato
Answer:
Native plants are those that occur naturally in a region in which they evolved. They are the ecological basis upon which life depends, including birds and people. Without them and the insects that co-evolved with them, local birds cannot survive. For example, research by the entomologist Doug Tallamy has shown that native oak trees support over 500 species of caterpillars whereas ginkgos, a commonly planted landscape tree from Asia, host only 5 species of caterpillars. When it takes over 6,000 caterpillars to raise one brood of chickadees, that is a significant difference.

Explanation:
if someone actually stole your DNA you wouldn't be alive right now,
but if someone stole "parts" of your DNA you would still be the same person because it doesn't matter what you look like you are your own person an example of this are identical twins, identical twins share the same exact DNA but they aren't the exact same person since they both can like different stuff and have different personalities. but if you mean in a biological stand point "if someone stole your DNA, could they steal your identity" of course not, at least not with our technology.

Blood passes through the left av valve as it moves from the _______ to the _______.
Answers
Answer:
left atrium; left ventricle
Blood passes through the left AV valve as it moves from the left atrium to the left ventricle.
The left AV valve is also known as the mitral valve or bicuspid valve. It is located between the left atrium and the left ventricle in the heart and allows blood to flow from the left atrium, where it has been collected from the lungs, into the left ventricle, from where it is pumped out to the rest of the body during the contraction of the heart.
Blood is a vital bodily fluid that circulates through the circulatory system of animals, including humans. The blood's primary functions include transporting oxygen and nutrients to cells, removing waste products and carbon dioxide from cells, regulating body temperature, carrying hormones, and supporting the immune system.

what is the nucleotide sequence of the dna template strand from which it was transcribed?
Answers
I'll be happy to help you. The nucleotide sequence of the DNA template strand from which it was transcribed is an important aspect of transcription.
It is important to note that in transcription, a DNA strand is transcribed into an RNA strand. During transcription, the DNA strands are separated, and the RNA is made by reading the sequence of the DNA template strand. The RNA polymerase enzyme adds RNA nucleotides that are complementary to the nucleotides in the DNA template strand.Here is the nucleotide sequence of the DNA template strand from which it was transcribed:5'-ATG CGG TTA CCA CGA GTA GTC-3'Explanation:During transcription.
DNA template strand is transcribed to mRNA, which is a single-stranded molecule that is complementary to the DNA template strand. The sequence of RNA nucleotides added during transcription is determined by the sequence of nucleotides in the DNA template strand. Therefore, the nucleotide sequence of the DNA template strand is complementary to the mRNA sequence, but it is read in the 3' to 5' direction.

Sickel cell anaemia is caused by a recessive allele. What evidence for this is there in figure 2?
Answers
In figure the second generation is unaffected and the third generation is effected which shows that sickel cell anemia is a recessive trait.
What is sickel cell anemia?
A genetic disorder called sickle cell anemia manifests from birth. The changed or mutated genes from your mother, father, or both parents are the root cause of many genetic disorders.Red blood cells in sickle cell anemia sufferers have a crescent or sickle shape.A hemoglobin gene mutation is the cause of this odd form. Red blood cells' hemoglobin component enables them to carry oxygen to tissues all over your body.Red blood cells' sickle shape can cause a number of difficulties. They can get caught inside blood arteries because of their atypical structure, resulting in uncomfortable symptoms.Furthermore, sickle cells age more rapidly than regular red blood cells, which can cause anemia.What are dominant and recessive allele?
Your mother and father each contributed one copy of each gene that makes you up. An allele is a gene's individual copy. Each parent may give you a dominant allele, a recessive allele, or a combination of both.Hence their name, dominant alleles typically take precedence over recessive alleles.Hence, A recessive allele of the hemoglobin gene is responsible for the sickle cell anemia trait. This means that in order to have the condition, you must have two copies of the recessive allele — one from each parent.

7.2.a1: the promoter as an example of non-coding dna with a function outline the role of promoter dna.
Answers
The promoter region of non-coding DNA plays a critical role in regulating gene expression by providing binding sites for transcription factors and initiating transcription by RNA polymerase.
The primary function of the promoter is to regulate the initiation of transcription. It contains specific DNA sequences, such as the TATA box and other regulatory elements, which provide binding sites for transcription factors. These transcription factors recognize and bind to the promoter region, facilitating the assembly of the transcription initiation complex. The RNA polymerase then binds to the promoter and initiates the synthesis of mRNA by unwinding the DNA strands and reading the template strand.
The promoter sequence determines the efficiency and specificity of gene transcription. Variations in the promoter region can influence the binding affinity of transcription factors, thereby modulating the rate of transcription. Additionally, regulatory elements within the promoter region can respond to signals and environmental cues, allowing for tight control of gene expression in response to various stimuli.

If the zygote contains unique cell contents that are necessary for gut differentiation, segregation of these substances during cell divisions would occur in the sequence of zygote to P1 to: _____
Answers
If the zygote contains unique cell contents that are necessary for gut differentiation, segregation of these substances during cell divisions would occur in the sequence of zygote to P1 to E to M to C. The zygote will undergo mitosis and form two daughter cells called P1. These P1 cells will undergo further divisions and differentiate into the endodermal (E) and mesodermal (M) cells.
The endodermal cells will form the gut and related organs, while the mesodermal cells will form the musculoskeletal and circulatory systems. The ectodermal (C) cells will form the skin and nervous system. Therefore, the sequence of zygote to P1 to E to M to C is essential for the proper development of the gut and other body systems.
segregation of these substances during cell divisions would occur in the sequence of zygote to P1 to the next stage, which is the formation of blastomeres.
The blastomeres result from the cleavage divisions of the zygote, and these cells will eventually differentiate to form various tissues and organs, including the gut, as the embryo continues to develop.

Explanation:
CORRECT me if I'm wrong.
#Carryonlearninh
If at start there are 60 chromosomes and ending with 30 chromosomes, then the process is meiosis. The correct option is C.
What is meiosis?Meiosis is a type of cell division that occurs in reproducing organisms and results in a reduction in the number of chromosomes in gametes (or egg and sperm).
Body (or somatic) cells in humans are diploid, with two sets of chromosomes (one from each parent).
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
Without meiosis, the number of chromosomes in a species does not remain constant across generations and is duplicated every time after reproduction.
Without meiosis, an organism cannot reproduce effectively through reproduction.
As, meiosis is equational division, and the chromosome number is also getting reduced to half, it can be meiosis.

Describe how increasing salinity affects the amount of fluid ejected each time a contractile vacuole contracts. Calculate the water potential (Ψ) of an animal cell without contractile vacuoles if water enters the cell and creates a solute potential (ΨS) of −2. Assume that the pressure potential
(ΨP) in the cell is 0.
Answers
Increasing salinity reduces the amount of fluid ejected by contractile vacuoles during contraction.
Increasing salinity negatively affects the functioning of contractile vacuoles in regulating water balance within the cell. The contractile vacuole works by collecting excess water and expelling it from the cell to maintain proper hydration levels. Higher salinity levels outside the cell create an osmotic gradient, causing water to move out of the cell at a faster rate.
This results in a reduced amount of fluid available for ejection during each contraction of the contractile vacuole. Consequently, the cell may struggle to maintain osmotic balance, leading to potential dehydration and cellular dysfunction.
water entering the cell would dilute the solute concentration, reducing the solute potential (ΨS). Assuming a pressure potential (ΨP) of 0, the water potential (Ψ) of the cell would be equal to the solute potential (ΨS) of -2.

A scientist notices that cells being grown in culture have ceased to divide. Further investigation demonstrates the cells have abnormally segregated chromosomes. Which checkpoint are these cells likely arrested at?
Answers
The cell cycle is a series of events that take place in a cell leading to its division into two daughter cells. The cells are likely arrested at the spindle checkpoint.
It is controlled by a series of checkpoints that ensure the fidelity of DNA replication and accurate chromosome segregation. The three major checkpoints in the cell cycle are the G1 checkpoint, the G2 checkpoint, and the M checkpoint.
In the given scenario, the cells have abnormally segregated chromosomes, which indicates that they are likely arrested at the M checkpoint.
The M checkpoint is also called the spindle checkpoint, which ensures that all the chromosomes are correctly attached to the spindle fibers before the cell enters anaphase, the stage of cell division where chromosomes are separated.
Abnormal segregation of chromosomes could occur due to various reasons such as errors in DNA replication, improper assembly of spindle fibers, defects in centrosome function, or abnormalities in kinetochore-microtubule attachments.
Whatever the cause may be, the M checkpoint plays a critical role in ensuring proper chromosome segregation and preventing the formation of aneuploid daughter cells with an abnormal number of chromosomes.

The cells are likely arrested at the mitotic checkpoint, also known as the spindle checkpoint or M checkpoint. This checkpoint occurs during metaphase of mitosis and ensures that all chromosomes are properly attached to the spindle fibers before the cell progresses to anaphase. If any chromosomes are not attached, the checkpoint stops the cell cycle and allows time for corrections to be made before cell division proceeds.
