It decreased in frequency over time.
It became extinct.
It is carried on a recessive allele.
It decreased in frequency over time.
Trait B decreased in frequency over time. So, the correct option is A.
What is trait?A trait is an attribute or characteristic of an organism that is influenced by its genes, according to genetics. Behavioural and physical characteristics, including intelligence and friendliness, can be altered by a combination of hereditary and environmental variables.
A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.
Hence, the correct option is A.

The correct answer is B) lowlands.
Coastal plains are also referred to as lowlands.
This region of the United States is a flat land next to the sea. Oftentimes this region is divided from other parts by mountain chains. We are talking about the coastal plains along the Atlantic Ocean. This low relief region of the East Coast extends for 2,200 miles from the state of New York to the state of Florida.

how does natural selection apply to an individual?
Answer:
read below
Explanation:
Individuals with adaptive traits, traits that give them some advantage are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Through this process of natural selection, traits are transmitted through generations and generations.

Can someone please help me I am doing a project were I have to wet a cloth and wrap it around a thermometer. Then I have a dry cloth and wrap it around another thermometer. The degrees for the wet one was 40 degrees and the dry one was 35. I had to do it three times and the dry one was still 35 on three trys and the wet one was still 40. now calculate the average. (f degrees - 32) x 5/9= the celsius
Answer:
Explanation:
35 + 35 + 35 + 40 + 40 + 40
(the numbers are there three times due to each trial value. you have to account for each.)
From the math you get 225.
Divide 225 by six due to their being six values
37.5 would be the average without the (f degrees-32) x 5/9
(now following the formula you put ((dont know if you have to follow though)))
37.5 - 32 x 5/9 = 3.055555556 degrees celcius.

What do prokaryotes have in common with eukaryotes?
A. They both have a Golgi apparatus.
B. They both have mitochondria.
C. They both have a nuclear membrane.
D. They both have a liquid cytoplasm.
Answer:
They both have a liquid cytoplasm.
Explanation:
A liquid cytoplasm is an essential part of a cell, in both prokaryotes and eukaryotes. It supports the internal components of the cell, and is the site of many vital cellular processes, such as glycolysis (the first part of cellular respiration).
The Golgi apparatus and the mitochondria are membrane-bound organelles that serve a specific purpose in eukaryotic cells. However, prokaryotic cells do not contain any membrane-bound organelles.
Prokaryotes do have a nucleus, like eukaryotes, but unlike in a eukaryotic cell, a prokaryotic nucleus is not surrounded by a nuclear membrane. Instead, it is just confined to a certain area of the cell, called a nucleoid.
Prokaryotes and eukaryotes both have a nuclear membrane. Option C
What is the commonality?
Prokaryotes and eukaryotes are two large categories of cells with notable variations in their organization and structure. They do, however, have some things in common.
The existence of a nuclear membrane or nuclear envelope is one of the similarities between prokaryotes (such as bacteria) and eukaryotes (such as plants, animals, fungi, and protists). The cell's genetic material, which can be either DNA or RNA, is encased in the nuclear membrane. It divides the cellular components into the nucleus and the remainder.

Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.
Which statements regarding hypotheses are true?
