Answer:
below
Explanation:
True.
Membrane Fluidity: The plasma membrane is a fluid combination of phospholipids, cholesterol, and proteins. Carbohydrates attached to lipids (glycolipids) and to proteins (glycoproteins) extend from the outward-facing surface of the membrane.
1. Hypothesize An aquarium hobbyist wants to breed guppies with large, fan-shaped,
red tails. The hobbyist has a large number of guppies with assorted tail colors and
shapes in an aquarium. Write a hypothesis that explains how the hobbyist should
proceed to breed a population of guppies with the desired traits.
They should separate pure lines (red fan-shaped tails) to cross them with other phenotypes and then observe phenotypic proportion in the offspring. It is Mendelian genetics.
What is Mendelian genetics?Mendelian genetics refers to the process of observing the phenotypic proportions from a given genetic cross.
Mendelian genetics is always associated with a genetic process known as complete dominance.
Complete dominance occurs when the recessive allele is completely masked in heterozygous individuals.

can someone calculate the genotypes and phenotypes of this pls
Say this was about breeds of chicken nuggets, some with and some without these features, then we can say that the genotypes of this nugget must be just that, mostly nugget, but due to certain influences, there will be some part that is not just nugget, so:
More than 80% nugget
Less than 20% non-nugget genotype.
This means that the phenotype, that shows up, is something similar to this: a mostly nugget being.

A type of genetic inheritance in which two phenotypes are seen together on the offspring is known as:.
Answer:
Codominance
Reason:
A codominance connection exists between two copies of a gene. Individuals inherit one copy of a gene, known as alleles, of each parent. If they are different , the allele that is dominant will typically be displayed, while the influence of the other allele, the recessive, will be concealed.
Answer:
Codominance
A codominance connection exists between two copies of a gene. Individuals inherit one copy of a gene, known as alleles, of each parent. If they are different , the allele that is dominant will typically be displayed, while the influence of the other allele, the recessive, will be concealed.
Explanation:
A codominance relationship exists between two gene copies. Individuals may develop one copy of both parent's genes., known as alleles. If they vary, the dominant allele will usually be visible, while the effect of the recessive allele will be hidden.

The type of molecule represented below is found in organisms.
Which statement correctly describes the sequence of bases found in this type of molecule?
A) It changes every time it replicates
B) It determines the characteristics that will be inherited
C) It is exactly the same in all organisms
D) It directly controls the synthesis of starch within a cell
Answer:
B) It determines the characteristics that will be inherited
Explanation:
The molecule is DNA (it has a double helix structure) which contains genetic information needed for every living organism.
Hope this helps!
Answer:
D
Explanation:
A and C are so incorrect. The reason why D is the correct answer is because DNA does not determine what gets inherited, just what gets added to the gene pool.
DNA does however control the synthesis of proteins by acting as instructions. Then these instructions are read and carried out by RNA to finally complete the process.

An animal can wound a tree by scratching away the bark.. The tree can respond to the wounded many ways. Usually sapped quickly covers the wound, and then the tree covers the wound with new growth.
The diagram below shows a cross-section of the tree with a healed wound. What process works most directly with the transport system to heal the wound.
a. cellular reproduction
b. photosynthesis
c. water intake
d. carbohydrate system
Answer:
the answer is A, cellular reproduction.
Explanation:
because cellular reproduction is a process by which cells duplicate their contents and then divide to yield multiple cells with similar, if not duplicate, contents, basically reforming itself again.

Why is a series circuit not a good way to wire a house? Question 5 options: Any break in a series circuit, such as a burned-out light bulb, will turn it into a parallel circuit. Any break in a series circuit, such as a burned-out light bulb, will result in overloading all the other light bulbs. Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit. Any break in a series circuit will result in a fire.
The correct answer is option Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit as it explains the disadvantage.
A downside of collection circuits is if there may be a ruin or fault at any of the home equipment related to the circuit, the last home equipment could be reduced from the supply. Regarding parallel circuits, home equipment may be related and disconnected to the circuit without affecting different components of it.
What will happen if the bulb will burn out?if one bulb burns out in a sequence circuit, then this could ruin the circuit. This is due to the fact each tool in a sequence circuit needs to paintings well for the circuit to be complete. Unlike in a parallel circuit - in which every mild has its personal circuit - so despite the fact that one bulb burns out, the last bulbs will nevertheless function.
Hence concluded that Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit can cause severe damage.

How is DDT spraying for malaria different from spraying for agriculture?
Evidence from countries that continued using DDT showed that correct and timely use of indoor spraying can reduce malaria transmission by up to 90%. In the past, India was able to use DDT effectively to substantially cut the number of malaria cases and deaths.
It also was effective for insect control in crop and livestock production, institutions, homes, and gardens. DDT's quick success as a pesticide and broad use in the United States and other countries led to the development of resistance by many insect pest species.
