Answers

Answer 1
Answer: the answer is phospholipids
Answer 2
Answer:

Answer:

Phospholipids

Explanation:

Cell membrane is an important type of cellular structure in the cells of living organisms. It functions to allow selective movement of materials or substances in an out of the cell.

Cell membrane is made up of a phospholipid bilayer and proteins embedded in it. Phospholipids form this lipid bilayer which is the basic structure of the cell membrane. The membrane also contains cholesterol molecules which help in keeping the membrane fluid consistent.

Additionally, the membrane also contains proteins whose function is to enhance the transportation of materials across the membrane.

You have a batch of tomato plants with hairy stems that you grew by crossing plants that had hairy stems (HH) with plants that had non-hairy stems (hh).Which will be expressed in this batch of tomato plants?



A.


non-hairy stems (recessive).


B.


hairy stems (dominant).


C.


hairy stems (recessive).


D.


non-hairy stems (dominant).

Answers

The answer is B. hairy stems (dominant).

If:
H - the dominant allele for hairy stems,
h - the recessive allele for non-hairy stems,

then:
HH - dominant homozygote with hairy stems,
Hh - heterozygote with hairy stems,
hh - recessive homozygote with non-hairy stems.

In autosomal dominant traits, the phenotype is present if both copies of the dominant allele (H) are present (homozygous individuals HH) or only one copy of the dominant allele is present (heterozygous individuals Hh).
In this case all of the batch of tomato plants were heterozygous individuals Hh with hairy stems:

Parental generation:        HH      x      hh
F1 generation:            Hh     Hh     Hh     Hh

Why is burning coal a major source of pollution?

Answers

It releases carbon dioxide into the air

Answer: DON'T COPY/PASTE

Coal is a chemically complex fuel. Whenever it is burned, gases are given off and particles of ash, called "fly ash," are released. The sulfur in coal combines with oxygen to form sulfur dioxide, which can be a major source of air pollution if emitted in large enough quantities.

The separation of soil into distinct layers is _______. A. horizonation B. soil reaction C. soil structure D. soil color

Answers

The separation of soil into distinct layers is called "horizonation ," which is preset in Option A, as this is the process where each layer represents a different stage of soil development with unique properties.

What is the significance of the horizonation of soil?

Horizonation is significant as it explains the separation of soil into distinct layers and provides information about the soil's history, development, and fertility with unique characteristics, such as color, texture, and density, while the top soil is the most fertile. While the middle and substratum layers provide information about the soil's foundation and are important for understanding the soil's history and composition,

Hence, the separation of soil into distinct layers is called "horizonation ," which is preset in Option A, as this is the process where each layer represents a different stage of soil development with unique properties.
