Explanation:
In addition to the vestigial leg bones and the series of transitional species in the fossil record, there is physiological and genetic evidence.
The physiological evidence is that whales swim with a modified running motion. If they had been specially created in the sea, there is no reason to have this holdover from life on land to let them swim.
Evidence for a horizontal fluke comes from the muscle attachments to move that fluke. Muscles pull on bone when they contract. Therefore bones have little bumps (sometimes not so little) on them as they add bone to handle the mechanical force of the contractions. Flukes can be inferred by the placement and size of the bumps on the vertebrae where the muscles that move the fluke (tail) are attached. Flukes themselves are soft tissue, and thus do not preserve well. But the bumps on the bone show a clear preference for muscle attachments on the top and bottom of the vertebrae, and these bumps get larger as the muscles evolve to be larger to move the fluke. If there is any other explanation and another inference, creationists have not provided it.
There is also the position of the nostrils over the course of evolution.
What is the purpose of nitrogen-fixing bacteria?
Answer: The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development. brainliest?

what process is responsible for the formation of glomerular filtrate
Answer:
The process by which glomerular filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.

The diagram below represents an energy pyramid constructed from data collected from an
aquatic ecosystem. Which statement best describes this ecosystem?
A.The ecosystem is most likely unstable.
B.The herbivore populations will continue to increase in size for many years.
C.Long-term stability of this ecosystem will continue.
D.The producer organisms outnumber the consumer organisms.
Energy pyramids are the models that show the flow of energy from the primary to the next level. From the energy pyramid, it can be said that long-term stability will be continued. Thus, option C is correct.
What are energy pyramids?Energy pyramids are the representation of the energy levels and the primary producers and other consumers. The producers are the base of the pyramid followed by the primary consumers.
In an aquatic ecosystem, the algae are the primary producers that provide energy to plankton and act as primary consumers. These are get eaten by small fishes and large fishes. The number of consumers gets decreased as one rises to the upper level.
Therefore, option C. an aquatic ecosystem will have stability.

Which of the following would NOT be considered growth and development?
A. a single cell getting larger before dividing
B. an egg becoming multiple cells
C. an organism going through multiple stages of life
D. group of molecules that are attracted together to form a larger sheet
Group of molecules that are attracted together to form a larger sheet is not considered as growth and development. The correct option is D.
What is growth and development?Development is defined as an increase in psychomotor capacity, while growth is defined as an irreversible constant increase in size.
Both processes are heavily influenced by genetic, dietary, and environmental factors.
Growth is defined as a person's development in weight, age, size, and habits.
Development, on the other hand, is defined as the process by which a person's growth is visible in relation to physical, environmental, and social factors.
Growth simply means an increase in the size and mass of a specific organism over time.
Development is defined as the method by which a specific organism transforms itself from a solitary cell to a more complex multicellular organism.
Thus, the correct option is D.

A carrier mother (XHXh) of hemophilia marries a normal father(XHY). *Use allele letter H What are the mothers and fathers genotype?
Answer: The mother of the man can be either XHXH or XHXh and pass her normal allele to the son and his father can be either XHY or XhY, he only passes his Y chromosome. The mother of the woman can be XHXH or XHXh and the father could be XhY, then she could have inherited the normal allele from the mother and the affected allele from the father. But also, the mother of the woman could be XHXh or XhXh and the father could be XHY, so in this case she could have inherited the normal alele from the father and the affected allele from the mother.
Explanation:
Hemophilia is an inherited bleeding disorder in which the blood does not clot properly. This can cause bleeding either spontaneously or after an injury.
It is related to the X chromosome and it is recessive for females, this mean they need both affected alleles to develop the trait. Males only need one recessive allele because they only have one X chromosome. This means that females need both parents to be at least carriers (although one or both can also have the disease or both recessive alleles). While males inherit it only from the mother, either she is a carrier (one recessive allele) or she has the disease (both recessive alleles). Then the mother passes the X chromosome with the affected allele to the son, and that son only receives the Y chromosome from the father, which does not have the gene that determines this disease.
If the mother is a carrier, her genotype is XHXh, being XH the normal allele and Xh the affected allele. She does not have hemophilia because she has a dominant allele. The father is XHY, so he does not have the disease because his only allele is normal (dominant)
The mother of the man can be either XHXH (she can only pass a normal allele) or XHXh and pass her normal allele to the son (in this case, the recessive allele is not inherited by chance.) His father can be either XHY or XhY, he only passes his Y chromosome which is not related to the disease. The mother of the woman can be XHXH or XHXh and the father could be XhY, then she could have inherited the normal allele from the mother and the affected allele from the father. But also, the mother of the woman could be XHXh or XhXh and the father could be XHY, so in this case she could have inherited the normal alele from the father and the affected allele from the mother.

What is the difference between mechanical digestion and chemical digestion?
Answer:
So, Mechanical and Chemical Digestion is the way of breaking down foods in the body. The difference between Mechanical and Chemical Digestion is, Mechanical Digestion involves the body's movement to make the food smaller and Chemical Digestion involves enzymes to break the food down.
Explanation:
Since Mechanical Digestion involves moving around to break the food down, you would get up and walk around a little to burn it to make it work and Chemical Digestion is just using the natural enzymes in the body to break food down.
Mechanical digestion is associated with the mouth. You mechanically chew the food and saliva (spit lol) breaks it down. Chemical digestion is in the stomach in which stomach acid breaks it down!
