Answer: Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled. The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted.
Explanation:
Genes A, B , C and D are present on the same chromosome. The recombination frequency between the genes is as follows: A and B: 24%, A and D: 16%, B and C: 18%, C and D: 10%. What is the correct order of genes along the chromosome
Answer:
BDCA
Explanation:
Recombination, also know as crossing-over, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during cell division (meiosis). The recombination frequency refers to the frequency of crossover between two genes/loci during meiosis. The recombination frequency is not a direct result of the physical distance between genes/loci on the same chromosome, but this value provides a good approximation of such distance. The recombination frequency is measured in centimorgans (cM), where 1 cM is equal to a 1% chance of recombination. The higher the recombination frequency between two genes/loci, the greater the chance that a cross-over will occur between them, and the greater the distance between them. Moreover, the lower the recombination frequency between two genes/loci, the lower the probability that they will separate by recombination, and the more closely they are linked.

All animals adapted to live in the coniferous forest?
Question 6 options:
True
False
Answer:
False , not all animals did.
Here are some animals that did adapt to the coniferous florets: red fox, moose, snowshoe hare, great horned owl, and the crossbill.
All animals are not adapted to live in the coniferous forests. The given statement is false.
What are Coniferous forests?The coniferous forests are the forests which have their vegetation composed primarily of the cone-bearing needle-leaved or scale-leaved evergreen trees, that are found in areas which have long winters and moderate to high annual precipitation.
Most of the animals which migrate to the warmer climates once the cold weather begins as they could not adapt to the conditions of coniferous forests. Some animals have adapted to life in the taiga by hibernating when the temperature drops. Other animals have adapted to the extreme cold temperatures through the production of a layer of insulating feathers or fur to protect them from the cold.

what is the pollinating agent of Ornithophilous
Answer:
Birds? Nectarivorous birds
Explanation:
Hummingbirds rely on nectar for energy, and ornithophilous flowers need hummingbirds' assistance with pollination in order to reproduce. While the birds are feeding, pollen sticks to their beaks, which will rub off on the next flower they visit, pollinating it.

what are the nitrates is used to make?
Answer:
fertilizers
Explanation:
Plants use nitrates as a supply of nitrogen, which is needed to make proteins for healthy growth. Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces.

Explain how selective pressure differs when species are exposed to competitive versus consumption (e.g., predator/prey) interactions and describe how this affects their adaptation to the interaction
Explanation:
Apparent competition occurs when two individuals that do not directly compete for resources affect each other indirectly by being prey for the same predator (Hatcher et al. ... The opposite effect could also occur through a decrease in food resources for the predator

A. overtime racoons learn to get food from garbage cans.
B. over time a person increases muscle mass with exercise
C. overtime honeysuckle flowers developed a sweet smell to attract pollinators
D. overtime corn plants are bred to make larger corn cobs and kernels
Over time corn plants are bred to make larger corn cobs and kernels have occurred as a result of natural selection. Hence, option D is correct.
What is natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others.
The development of giraffes' long necks is a prime illustration of natural selection in action. Animals with necks of average length, like deer or antelope, were the ancestors of current giraffes.
Over time corn plants are bred to make larger corn cobs and kernels have occurred as a result of natural selection. Hence, option D is correct.

start fraction, 1, divided by, 10, end fraction of its value each year.
Write a function that gives the car's value, V(t)V(t)V, left parenthesis, t, right parenthesis, ttt years after it is sold.
Answer: V(t)=5000(9/10)^t
Explanation:
If the car loses 1/10 of its value each year, that means 9/10 of the value remains each year.
So each year, the car's value is multiplied by a factor of 9/10 or 0.9
If we start with the initial value, $5000 and keep multiplying by 9/10 his function gives us the car's value t years from now:
Why is protein synthesis important when we talk about genetic variation?
Answer:
Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein. In the second step, translation, the mRNA is read by a ribosome. The key to a protein molecule is how the amino acids are linked. The sequence of amino acids in a protein is a type of code that specifies the protein and distinguishes one protein from another. A genetic code in the DNA determines this amino acid code.

Based on this information, what is the most likely relationship between common garter snakes and rough-skinned newts?
Explanation:
In evolutionary theory, the relationship between the rough-skinned newt and the common garter snake is considered an example of co-evolution. The mutations in the snake's genes that conferred resistance to the toxin have resulted in a selective pressure that favors newts which produce more potent levels of toxin.

PlS HELP 30 POINTS FOR BRAINLIEST!!!!!!!!!!!!!!!!!!
Answer:
It's a little difficult to see the difference between the finch 1 and finch 2 population lines, but their trends should match those of the food. This answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line: The finch 1 population has a beak adapted to eating seeds and the finch 2 population has a beak better adapted to eating fruit
Explanation:
Since we are given data for both the food source and the finch population, the answer will most likely reflect that. Therefore eliminating choices A (disease) and C (feathers). Again, this answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line. The lines for the finch population will match with the availability of food, so less seeds mean less finch 1 and when the amount of seeds rise up you can see the population of finch 1 also rises.
