What is the genotype of the parents if allele b is dominant over allele b?.
The dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.
What is genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual possesses in a certain gene or genetic region are also referred to as the genotype.
The amount of copies of the each chromosome contained in that species, commonly known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person possesses two alleles for each gene. The dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.
Therefore, the dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.

Answer:
D
Explanation:
Aseual reproduction is a type of reproduction in which new organisms are reproduce from single parent without production of gametes. But in D their is fusion of gametes (egg and sperm) therefore it explains to us that it is not an aseual reproduction.
If you soak seeds in water to soften them, and then cut them in half and stain them with iodine, most of the inside of the seed will change color, turning a purplish-black. What substance is the iodine reacting with to cause this color change?
Answer:

Explanation:
Starch consists of amylopectin and amylose, and is found in plants. In the presence of iodine, amylose starch turns a dark purple or blue color, due to the absorption of different wavelengths of light than before.

For this assignment, you will develop a model to describe the cycling of matter and the flow of energy
among living and nonliving parts of an ecosystem. This project includes both an individual and a group
part. On your own, you will research an organism that is assigned to you. In your group, you will combine
your organism with the organisms researched by other students to create a food web. Together, you will
write two short paragraphs explaining how energy and matter move through the food web.
Answer:
All I can tell you is when energy is moves through the food web it gets divided by 10
plant energy =1 0,000 (example)
that plant gets eaten by a small animal
small animal's energy gained from the plant = 1,000
a large animal then eats the smaller one
large animal's energy gained from the small animal = 100
Explanation:
I am sorry you will have to write your two short paragraphs on your own.

Explanation:
how is an increased in carbonin the atmosphere likley to affect coastal areas such as those in north carolina
Answer:
D
Explanation:
The amount of Carbon dioxide (CO₂) that is trapped in the atmosphere is released by the burning of the fossil fuels and from the industrial pollution. In addition to this, some amount of it also released by the animals and human beings. This stored CO₂ in the atmosphere is then transported to the oceans with the help of rainfall. When this CO₂ reacts with water it forms weaker acid, which is commonly known as the Carbonic acid. Due to this, the pH level of ocean water decreases. As a result of this, it affects the ocean water chemistry and the marine life. Due to this ocean acidification, the marine species namely the corals and various types of planktons are not able to form the hard parts like the shell and skeletal parts. This carbonate water dissolves the existing shells and erodes the particles away. The increase in the carbon content in the atmosphere will also lead to precipitation that will wash away the rock particles and other sediments, that are present in the coastal areas. In addition to this, the plants also will be affected due to this carbon containing water.

Why is it important to design field studies that will not make wild animals associate humans with food?
Animal behaviorists have found that animals gain from developing bonds with trustworthy humans, but doing so calls for a lot of motivation and understanding about the animal's behavior.
What is animal behavior?The scientific study of non-human animal behavior is called ethology, and it often focuses on behavior in natural settings and sees behavior as an evolutionary adaptive quality.
Animal behavior is an animal's response to stimuli, and there are both acquired and intrinsic types of animal behavior.
Dogs who have been trained to obey commands are an example of animal behavior. In contrast, inherent behavior includes mating cues like bird crowing and peacock dancing before a storm.
Animals benefit from forming relationships with dependable humans, according to animal behaviorists, although doing so requires a lot of drive and knowledge of the animal's behavior.
Anyone lacking sufficient motivation or missing the necessary knowledge could suffer considerable harm if they attempted to interact with the animal.
Thus, it is important to design field studies that will not make wild animals associate humans with food.

1. During the normal life of a somatic animal cell, which of the following puts the observed cellular
processes in order from interphase to cytokinesis using the pictures in Diagram 1?
The diagram is not found here, but the order of steps in the cellular division is interphase (G1, S and G2) >> mitosis >> cytokinesis. It is the cell cycle.
What is the cell cycle?The cell cycle refers to the events that occur from a cell form until it divides to produce two daughter cells.
The cell cycle can be divided into interphase, mitosis and cytokinesis (i.e., division of the cell cytoplasm).
Interphase has there main steps, i.e., Growth 1 (G1) phase, Synthesis (S) phase, and Growth 2 (G2) phase.
In turn, mitosis can be divided into prophase, prometaphase, metaphase, anaphase and telophase.
