what is the dominant impact that humans have on alpine glaciers?

Answers

The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.

Answer:

Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.

ln humans, red green color blindness is a sex-linked recessive trait. If a man and a woman produce a color blind son, which of the following must be true?

a. The father is color blind.
b. Both parents carry the allele for color blindness.
c. Neither parent carries the allele for color blindness.
d. The father carries the allele for color blindness.
e. The mother carries the allele for color blindness.​

Answers

B is the answer
If it’s a recessive allele 1 parent isn’t enough, both parents have to have the recessive allele, and even then it’s a small chance. Hope this helped ^^

If a man and a woman produce a color blind son then both parents carry

the allele for color blindness.

A trait could either be:

DominantRecessive

What is a Recessive trait?

A recessive trait is usually expressed when there is the presence of two

recessive alleles in an individual or organism. A dominant  trait on the other

hand can be expressed with the organism having only one dominant allele

In this scenario, the red green color is a recessive trait

and the offspring produced is color blind which basically means that both

parents carry the allele for color blindness.

a/an ___ is a blood clot attached to the interior wall of a vein or artery.

Answers

Answer: a thrombus

A thrombus may also form in your heart

A thrombus is a blood clot attached to the interior wall of a vein or artery, which is option a. So the correct option is option a, as thrombus formation occurs when blood coagulation factors are activated and form a clot within a blood vessel.

Thrombi can occur in veins (venous thrombosis) or arteries (arterial thrombosis). In veins, a thrombus can lead to deep vein thrombosis (DVT), which commonly occurs in the lower extremities. If a thrombus dislodges from its site of origin and travels through the bloodstream, it is called an embolus, and it can potentially cause an embolism in another location. So the correct option is option a.

what factors determine if a species is fit to survive?

Answers

Answer: variation, reproduction, and heritability.

Explanation:  Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.  

All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.

Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.
