What functions does the red blood cell do for a human?
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:
Which system is responsible for creating red blood cells?
a
skeletal
b
muscular
c
nervous
d
circulatory
A mountain range divides a freshwater snail species into two large isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of:
Answer:
allopatric speciation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction.
II. Asexual reproduction.
In this scenario, a freshwater snail species is divided into two (2) large isolated populations by a mountain range. This range is then lowered by an erosion and as such bringing the two populations of the freshwater snail species together again.
However, when the two snail species mate, the resulting hybrids all produce sterile young snails. Thus, this scenario is an example of allopatric speciation.
Allopatric speciation is also referred to as geographical speciation and it can be defined as a process in which two (2) biological populations of the same species become isolated from each other by geographical barriers or changes such as mountain range, emigration, etc. Thus, allopatric speciation is dominant with living organisms that reproduces sexually and it causes the isolated species to evolve newly with distinctive traits.
How do humans help plants during photosynthesis?
Answer:
Humans breathe out carbon dioxside which plants need to live and grow during the process of photosynthesis.
Explanation:
They do this by a process known as photosynthesis. ... Photosynthesis and respiration are the two essential processes that allow life to sustain on earth. In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and humans help plants "breathe" by providing them with carbon dioxide.

In humans, dimples are dominant to no dimples and freckles are dominant to no freckles. A man with
no dimples or freckles mates with a woman who is heterozygous for both traits. Determine the
percentage of their offspring that will have the same genotype as their mother. Also determine the
percentage of their offspring that will have the same phenotype as their father.
Answer:
I'm being honest the answer are in the pdf pls don't report me its not a scam
Explanation:
The correct answer is 25% of their offspring will have the same genotype as their mother.
25% of their offspring will have the same phenotype as their father.
What is genotype?The term genotype refers to an organism's whole complement of genes; in other words, it describes its genetic composition. In a more restricted meaning, the phrase can refer to the alleles, or alternative forms of a gene, that an organism carries.
what is phenotype?A phenotype is just an observable trait. Pheno means observe and is derived from the same root as "phenomenon." As a result, it's an observable sort of organism that can refer to anything from a common characteristic like height or hair color to the presence or absence of a disease.

Which of the following best illustrates the idea of Survival of the Fittest?
A.
The strongest ant in the colony always gets the most mates.
B.
The strongest cow always eats the most grass.
C.
A slower cheetah is able to obtain more food than others because it is able to catch the slower deer while the faster cheetah goes after the fastest deer.
D.
The largest mouse always wins even though it is more easily seen by predators.
Answer:
The correct answer is - Option A. The strongest ant in the colony always gets the most mates.
Explanation:
The survival of fittest is the idea that is developed from the theory of evolution proposed by Darwin in his book Origin of Species. This phrase is used to explain the mechanism of natural selection. According to natural selection which is a process the species that adapt the ecological changes in order to survive and reproduce themselves, carry the traits to the next generation.
The ant colony has different classes on the basis of their role and strength. The queen is most strong ant that can produce offspring by mating with most of the mates.
A young man claiming to be the son of Howard Hughes is suing the estate for his inheritance. Hughes (multimillionaire, inventor, businessman, and subject of the 2004 film, Aviator), did not leave behind any heirs upon his death. The judge overseeing this case, orders blood tests. Howard Hughes has blood type AB, the mother of the young man has type A blood, and the young man had type O. If you were the judge in this case, what would be your ruling?
Answer:
The young man is not the son of Howard Hughes.
Explanation:
The human blood system works on codominance type of inheritance in the case of blood group A and blood group B present together however, in blood group O it still follows the law of dominance as antigen O is recessive in present of any other antigen.
We know Howard Hughes had blood type AB
So, the genotype would be - IAIB
We also know that the mother of the young man claiming has a blood type A
So, possible genotypes would be - IAIA (case 1) or IAi (case 2)
For case 1,
The possible genotypes for the man claiming would be
IAIB X IAIA --------> IA IA, and IAIB.
According to case 1, he is not the son of Howard.
For case 2,
The possible genotypes for the man claiming would be
IAIB. X I A i ---------> IA IA , IAIB I A i and IB i
Both cases show that the man claiming is not the son of Howard as the blood group of the man is O and the genotype should be ii.

The most common form of hemophilia is a defect in blood clotting factor VIII, which is caused by a mutant form of a gene on the X chromosome. Boys who inherit that mutation from their mother suffer from uncontrolled bleeding. Girls carrying one copy of this mutation have near normal blood clotting. Uncommonly, a girl is born with hemophilia even though both parents have normal phenotypes. Which of the statements might explain hemophilia in a girl born to parents with normal blood clotting phenotypes?
Answer:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.
Explanation:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.
It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.
However, such mutant (X) communicates and expresses itself and she is hemophilic.
This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.
