The United States Arctic National Wildlife Refuge is a large portion of Alaska that is protected from construction, which would affect the land and resources that are available to living things. Which term is used to describe all the species that live in the Arctic National Wildlife Refuge?

Answers

Answer:

The term that is used to describe all the species, which lives in the Arctic National Wildlife Refuge is community.

Explanation:

The community also considered as the biological community signifies towards an associating group of distinct species in a specific location. For example, the plants grown underneath and a forest of trees, inhabited by animals, and the roots in soil constituting bacteria and fungi, leads to the formation of a biological community.

Answer:

Explanation:

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. Think about the gametes this parent plant will produce. List the alleles in each gamete.

Answers

During gametes production, alleles randomly separate producing different combinations in daughter cells. The gametes in this example are YS, Ys, yS, ys.

How are gametes formed?

Gametes are formed during meiosis. Meiosis is a cell division process that produces gametes from germ cells. Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).

According to the segregation principle, alleles separate independently during gametes formation.

In anaphase I, homologous chromosomes separate, and each of them migrate to the opposite poles of the cell carrying one of the alleles. This random event leads to different chromosomal combinations in the daughter cells.

Now, let us analyze the problem,

Plant ⇒ heter0zyg0us for both seed shape and seed color ⇒ SsYy

S is the dominant allele and codes for spherical shape
s is teh recessive allele and codes for dented shape
Y is the dominant allele and codes for yellow
y is the recessive allele and codes for green

Gametes) YS, Ys, yS, ys.

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

Which statement best relates science and societal problems? Societal problems are the result of science. Any societal problem can be solved by using science. A scientific solution to a societal problem does not result in further problems. Science can be used to address societal problems, but it is not always successful.

Answers

The true statement is the following one!
Science can be used to address societal problems, but it is not always successful.

For example, let's take alcoholism. Science can help us better understand the causes and help prevent and treat it, but it's not always successful as people often fall back into the illness despite their treatment.
