D. The moose would be more able to protect its offspring.
SUBMIT
The answers are.
A. The moose would be more able to avoid predators.
C. The moose would be more able to chase and catch prey.
Explanation:
This moose population can use their speed to protect themself from the predators, but only protecting themself from predators won’t help them for their survival. They need food to live. Speed will help them to chase and catch the pray also. Since the population of moose in the Yellowstone National Park is less for them, it is very difficult to protect their territory by using their speed. They can use their speed to chase their prey. Maybe while chasing they ended up facing their predators, but they can use their speed to escape from them. Later, this will help them to make offspring also. Moose will be able to protect their offspring by running, but they should give food to the offspring also to survive.Answer:

Explain the function of Chromosomes. Use your knowledge of genes and DNA to
give your answer.
Final answer:
Chromosomes are structures comprised of DNA and proteins that contain genes, which code for proteins responsible for various traits and functions in the body. Humans have 23 pairs of chromosomes, including autosomes and sex chromosomes, with approximately 20,000 to 22,000 genes.
Explanation:
Chromosomes are essential structures within the cells of our body that carry out a vital role in heredity and gene expression. They are coiled structures composed of DNA and proteins, specifically histones, which help organize and condense the DNA into a compact form that can fit within the nucleus of a cell. During cell division, chromosomes ensure that DNA is accurately replicated and distributed to each new cell.
DNA within chromosomes is segmented into units called genes, which harbor the instructions for making proteins, the building blocks of our body. These proteins perform a multitude of functions, including building cellular structures, carrying out metabolic reactions, and responding to environmental signals.
Human cells normally contain 46 chromosomes, arranged in 23 pairs. Twenty-two of these pairs are autosomes, with the remaining pair being the sex chromosomes (XX in females, XY in males). The estimated 20,000 to 22,000 human genes are responsible for a huge variety of traits and functions. Genes contain the specific sequences of DNA that are transcribed and translated to create proteins. Each gene has multiple forms or alleles, which can result in variations in the physical manifestation of a genetic trait.

Answer: Three molecules of NADH is produced from every molecule of pyruvate that enters the Krebs cycle.
Explanation: Pyruvate produced from glycolysis is broken down to Acetyl CoA which then enters the Krebs cycle. In Krebs cycle, each molecule of acetyl CoA yields one molecule of GTP (ATP), one molecule of FADH2 and three molecules of NADH. The main purpose of Krebs cycle is to generate NADH needed in the cells. Krebs cycle is a series of eight enzyme catalyzed reactions which oxidizes the Acetyl CoA produced from pyruvate. The NADH molecules are produced by dehydrogenase enzymes:
1). Isocitrate dehydrogenase which converts isocitrate to alpha ketoglutarate.
2). Alpha ketoglutarate dehydrogenase which converts alpha ketoglutarate to succinyl CoA.
3). Malate dehydrogenase which converts malate to oxaloacete.

Explanation:
B is a gene for blue feathers,and b is a gene for red feathers. Two heterozygous birds have an offspring. What percentage chance does it have for red feathers. A 0 b 25 C
75 or D 100
Answer: b) 25
Explanation: B is a gene for blue feathers and b is a gene for red feathers, the genotype for a heterozygous bird is Bb. A cross between two heterozygous birds will produce 1BB, 2Bb and 1bb. Genotype BB and Bb will manifest outwardly as blue feathers while Bb will manifest as red feathers. Only one out of the four offsprings are red feathered. The percentage of the offsprings that are red feathered is 1/4 x 100 = 25
See attached for more information
When crossing two heterozygous birds (Bb) for feather color, the offspring have a 25% chance of being homozygous recessive (bb) and having red feathers. This is determined by the Punnett square, which predicts the genotypes of the offspring from the parental genes. B)
The question is asking about the probability of offspring with a particular phenotype given the genotypes of the parents. In this case, B represents a gene for blue feathers, which is dominant, and b is a gene for red feathers, which is recessive. When two heterozygous birds (Bb) are crossed, the Punnett square analysis reveals the probabilities for the offspring's genotypes and phenotypes.
Here is how you would set up the Punnett square:
Place one parent's alleles at the top of the Punnett square, B and b.
Place the second parent's alleles on the left side of the Punnett square, B and b.
Fill in the squares by combining the alleles from each parent to predict the potential genotypes of the offspring.
The resulting genotypes of the offspring will be:
BB (blue feathers, because B is dominant)
Two squares of Bb (also blue feathers because B is dominant)
One square of bb (red feathers because there is no dominant B allele present)
Thus, there is a 25% chance that an offspring will have red feathers (genotype bb).
So the correct answer is B, 25% chance for an offspring to have red feathers.

Explanation:
13. Having a long neck is a selective advantage for giraffes. Their long necks make them better suited to reaching food supply at the top of trees, improving their fitness and chances of reaching reproductive age and passing on traits to the next generation. This is how natural selection acts on these traits meaning that over time, giraffes evolve a long neck.
14. The variation in the mice tail length has shifted over time, which suggests that the frequency of the alleles that control tail length has changed. This is clear when you look at the peak of the graph, which has shifted towards longer tail lengths. This suggests alleles coding for longer tail lengths are becoming more common, with the loss of shorter tail lengths
15. If a mutation spontaneously appears in the rabbit genome that makes them resistant to the virus, then they are much more likely to survive than other members of their population. This selective advantage means they are more likely to reach sexual maturity and reproduce, passing the mutation on to the next generation, where they also will benefit. Rabbits breed a lot and quickly, so natural can happen reasonably quickly in these populations, meaning the numbers of resistant rabbits will rise.
16. A vestigial structure is one that is now redundant. That means that the organism no longer uses it. These remain because there are no real selective pressures acting on them that would cause their disappearance to accelerate. Instead, they remain. These bones indicate that at one point, whale populations used to have additional limbs, suggesting they evolved from four legged animals.
17. Changes in the genetic code of an organism can sometimes produce effects such as changes to protein structure, composition, and amount. These can have changes on a much larger scale such as in the structure of forelimbs. Beneficial changes will be positively acted on by natural selection. For example, a bat could develop a stronger wing structure for rapid flying, where as the whale forelimbs are very large to make them powerful in the water. Natural selection can only act on these changes if they are heritable, meaning they have to have changed in the DNA. Any physical changes not present in the DNA will not be passed on to the next generation or undergo evolution.
I need an example of Bacteria, Archaea, and Eukarya.
Answer:
Both Bacteria and Archaea are prokaryotes, single-celled microorganisms with no nuclei, and Eukarya includes us and all other animals, plants, fungi, and single-celled protists – all organisms whose cells have nuclei to enclose their DNA apart from the rest of the cell

Question 2 options:
Gravity only works between planets.
Gravity is a contact force that holds objects down on Earth.
Gravity is a contact force that holds the Moon in orbit around Earth.
Gravity is a non-contact force that holds the Moon in orbit around Earth.
"Gravity is a contact force that holds objects down on Earth" best describes gravity.
Answer: Option B
Explanation:
Gravity is the force which attracts two bodies one to the other. It is the force which causes objects in the air to fall to the ground and keeps the planets around the sun in their orbit. The greater an object's mass, the greater its gravitational power.
Gravity declines with elevation, near the Surface of the earth (sea level), so that at one-half of the Earth's radius, linear extrapolation will give zero gravity. The gravity of Planet originates from all of its mass. All its mass causes the whole mass in one's body a collective gravitational pull on.

What is the role of RNA polymerase?
It creates the DNA strand.
It bonds the DNA strand.
It helps transcribe the DNA strand.
It translates the DNA strand.
Answer:
RNA polymerase transcribes the DNA strand and synthesis RNA from a DNA template
The role of RNA polymerase is it helps in transcribing the DNA strand and forms mRNA (messenger RNA). Thus, the correct option is C.
What is Transcription?Transcription is the process of copying or transcription of a segment of DNA into RNA that is messenger RNA (mRNA). The segments of the DNA sequence transcribed into mRNA molecules that can encode specific proteins, which are said to produce messenger RNA. Other segments of the DNA molecule are copied into RNA molecules called non-coding RNAs (ncRNA). mRNA comprises only 1-3% of the total RNA samples.
Transcription occurs in the nucleus of the cell and the mRNA formed from this process is sent to the ribosomes for translation. The major steps of transcription include initiation, promoter clearance, elongation, and termination step.
Therefore, the correct option is C.

What can you conclude about the water quality of Sandy's pond over the past year? Explain. (5 points)
The water quality of the pond is worst in month of June and July. And the pH of the pond is mostly acidic, but went from alkaline in month of April. A.
Explanation:The pond quality assessment requires the measure of the pH of the water of pond and the number of colonies of bacteria and presence of other organisms in pond and their assessment. The report given here shows the variation of pond water pH for about 10 months and the colony count per liter for 10 months.
Here in the graphs given, we can see that the pond water quality got worst in month of June and July, because in those months, the water got the most number of faecal coliform bacteria. This is mainly because the months of June and July are the monsoon season, and the water sweeping from different areas of soil got the fecal coliform bacteria into the pond which helped in their growth and increased numbers.
In the month of March, the pH got to the highest of 7.5 which is because the March season don't generally get too much rainfall which is why the water concentration decreases and the growth of different other bacteria and plants make the water alkaline.
