why do veins have valves

Answers

Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.

Answer:

Lack of Antidiuretic hormone.

Explanation:

Antidiuretic hormone is a type of hormone which is responsible for controlling urination. It is produced in hypothalamus which is a part of a brain. Antidiuretic hormone is responsible to tell the kidney how much water in the body should be conserve to avoid dehydration. If less antidiuretic hormone is produced by the body so more urine is produced. Frequent urination is also occurs due to Diabetes insipidus.

What is Ependymal cell?

Answers

Answer:

Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.

Ependymal cells are ciliated-epithelial glial cells. It develops from radial glia alongside the surface of the ventricles of the brain and spinal canal.

What is the function of Ependymal cells?

The main role of Ependymal cells is formation of CSF.

The CSF refers to cerebrospinal fluid. It is done by movement of sodium ion, chlorine ion and bicarbonate ion from blood to ventricles of brain.

Inside ventricles of the brain, collection of ependymal cells and capillaries together i.e., the tela choroidea form choroid plexus, which produces the CSF.

Thus, Ependymal cells are involved in formation of CSF.

Answers

Answer:

Top predators at the highest trophic levels eat lower-level predators and herbivores

Explanation:

A trophic level is defined as one group of organisms in the ecosystem occupying the same level in the food chain, which is composed of different levels (primary, secondary and higher levels). Top predators at the higher levels maintain the trophic balance by eating other species that eat on primary producers/consumers, thereby favoring the homeostasis of the ecosystem.

If pattern of inheritance is complete dominance what would you expect when a red and yellow fish were crossed

Answers

In the question, it is not mentioned that which fish is dominant and recessive, so lets consider red fish is dominant and yellow fish is recessive.

Answer:

In complete dominance, the dominant trait completely masks the recessive trait and the offspring shows dominant characters only.

When a red and yellow fish were crossed, the pattern of inheritance is complete dominance which means the offspring would have dominant characters.

As we considered, red fish has dominant trait so the offspring produced will also have red color as yellow color (recessive) will be masked by dominant red color fish.

Discuss Connell and Slatyer three mechanisms of succession. Start your answer with a definition and an example of what is succession, and describe how succession begins.

Answers

Answer:

Facilitation, tolerance and inhibition models

Explanation:

J. H. Connell and R. O. Slatyer stated three different ecological succession models that explain how species composition may change by the effects of disturbances in the ecosystem. These models are as follow:  

1- Tolerance model: in this model, the new species don't affect the growth and success of existing species, thereby the process of succession is purely associated with life-history strategies.

2- Facilitation model: only 'ideal traits' found in colonizing species lead to the initial succession. These ideal traits include for example effective mechanism of dispersal, water storage tissues to survive in dry regions, long-term seed dormancy, etc.

3-Inhibition model: Species that appeared during early succession are capable of inhibiting growth of species appeared in later stages, as well as reduce colonizing species abundance.

Answer:

C and D  

Explanation:  

Layers C and D apparently contain the same fossilized organisms in the same substrate. Their appearance is very similar. By knowing that certain organisms used to live in a certain period of time, if we find two strata that show the same fossilized organisms, then we can estimate that these two strata are the same age. Fossilized organisms are used to estimate the age of a rocky stratum.

Life history can be illustrated through fossilized organisms trapped or converted into rocks. These fossils are known as index or guide fossils, of animal or vegetal nature, and they can apport information about the rocky stratum in which they are located or incrusted. These fossils are used to determine the age of the rocky sediments or the environmental conditions under which they were deposited.

n your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. You have two rattlesnakes, one rattlesnake has a mutation but can still produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: TATCGCTACGCACGTCAG

Answers

Answer:

There are no options but the kind of mutation that occurred by carefully observing both sequences is:

POINT SUBSTITUTION MUTATION

Explanation:

Mutation is any change, whether small or big, in the nucleotide sequence of a gene (DNA). Mutation occurs from time to time in an organism either by a mistake during DNA replication or induced by a mutagen (mutation-causing substance). Mutation can be of different types depending on the effect on the mutant.

In this case of comparing the DNA sequence two rattle snakes, the sequences of the two snakes are:

Normal: AATCGCTACGCACGTCAG

Mutated: TATCGCTACGCACGTCAG

By carefully observing the two DNA sequences, one would realize that the only difference in the two sequences is the first nucleotide base. That is, in the normal sequence, th first base is Adenine (A) while in the mutated sequence, the first base is Thymine (T).

This type of mutation that involves only one nucleotide base is called POINT MUTATION. It can also be noticed that base "A" was changed "T". Hence, this is a type of SUBSTITUTION MUTATION because a single base was replaced by another in the sequence.

Personalized genomic medicine  

Explanation:

Personalized genomic medicine is a field that uses genomics data to develop personalized technologies and therapies for clinical care. All people share a sequence homology level higher than 99%; however a very small fraction of the genome (lesser than 1%) contains genetic polymorphisms among individuals, and this variation is associated with the likelihood of suffering diseases, either by increasing or by reducing disease susceptibility. Personalized genomic medicine first identifies genetic variations and then develops new strategies and personalized drugs to treat genetic disorders.

a. use two fingers to attempt to reduce the mass.
b. palpate the left scrotum simultaneously.
c. lift the right testicle and then compare pain level.
d. transilluminate the mass

Answers

Answer:

d. transilluminate the mass

Explanation:

Sometimes, painless hard or tender mass develop in the scrotum of men and can cause testicular tumors.

After detecting a scrotal mass, to reduce the size of the mass, the next assessment required is to transilluminate the mass in which testicles will be appear opaque on transillumination. Transillumination of mass will help to detect the orientation of mass which can be treated further.

Hence, the correct answer is d. transilluminate the mass
