Answer:
Aa x Aa makes Aa because its a dominant gene. each square represents 25% so if u have 2 squares with Aa for example the ratio will be 2:4 (so 50%) if the gene is recessive then for the next generation it will go down to 25% unless another Aa allele is introduced in the next generation

Write 3 sentences about what you learned yesterday about phases of the moon.
Answer:
1) There are 8 main phases of the moon: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent.
2) A full moon occurs about once a month. (every 29.5 days to be exact)
3) The phases of the moon are caused by the light from the sun and the moon's orbit around the Earth.
A science class is doing an experiment on how light affects the growth of plants. One set of plants is placed under a special light, a second set
of plants is placed in the dark. A third set of plants is left under normal room lights. The class measures and charts each plant's growth for a

Whích statement is best supported by the diagram?
А.
Species T and Species U are related to species X
B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.

8. The sequence of DNA carries the genetic information of an organism
9. The process of mitosis produces a new copy of an organism's genetic information.
10. Two new molecules of DNA are created
Explanation:
Through this replication process two complete molecules of DNA are created from one DNA molecule, with a double helix structure. This event is important for every organism in order for they to grow, reproduce and repair.
There are many proteins and enzymes that take part in all these steps.
The correct order of DNA replication is:
1. Cell replication starts into the mitosis phase of the cell cycle.
2. Helicase begins to break the hydrogen bonds between nitrogen bases.
3. The double coiled shape of DNA is called a double helix.
4. DNA polymerase attaches the free-floating nucleotides to the exposed nitrogen bases.
5. Free-floating nucleotides pair up with exposed nitrogen bases.

8. The sequence of DNA carries the genetic information of an organism.
9. The process of mitosis produces a new copy of an organism's genetic information.
10. Two new molecules of DNA are created.
What is DNA replication?
DNA replication is the process by which a molecule of DNA is duplicated.
When a cell divides, it must first duplicate its genome so that each daughter cell winds up with a complete set of chromosomes.
Thus, the correct order of DNA replication is that.

describe two ways to transfer electric charge
.Answer: conduction or polarization
Answer:
conduction, friction
Explanation:
Friciton: When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.
Conduction: During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod.

Which of the following is NOT an example of natural selection?
A. Plants with thorns are less likely to be eaten by herbivores than other members of the same species that lack thorns.
B. Bacterial populations in hospitals develop resistance to drugs used to combat infection by them.
C. Scientists breed cows that give greater amounts of milk than their ancestors.
D. Fruit fly larvae with an enzyme to break down alcohol are better able to feed on fermenting fruit than those that lack the enzyme.
Answer:
The correct answer would be - C. Scientists breed cows that give greater amounts of milk than their ancestors
Explanation:
Natural selection is the process of adapting according to the new changes in condition and change accordingly to survive. So the individuals of organisms that are better and adapt faster to survive and reproduce better than others are the result of natural selection.
Plants developed thorns so they can be avoided by predators is the adaption and example of natural selection. Similarly, bacterial populations adapt and develop resistance to the drug. Fruit fly larva developed and adapt as well. Breeding cows for more amount of milk than ancestors by scientists is not natural selection.

Why is the structure of a
nucleosome so important?
Answer:
In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression
Explanation:
In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.
substance in which the monomer is a nucleotide _______
A - Carbohydrates
B - Nucleic Acids
C - Proteins
D - Fats
Nucleic acid is a substance in which the monomer is a nucleotide. Therefore, option B is correct.
What are nucleic acids?Biopolymers and macromolecules called nucleic acids are important for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base (adenine, guanine, thymine, uracil, and cytosine), a phosphate group, and a 5-carbon sugar.
The components that make up an individual's genetic code are nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid are the principal two examples of nucleic acids (RNA). They have an important role in heredity and protein synthesis.
Thus, A nucleotide serves as the monomer of a material known as nucleic acid. Therefore, option B is correct.

Explanation:
Can anyone help me with these please
Answer:
6. Current = 8.33 Amps
7. Energy = 1200 Joules
Explanation:
Given the following data;
6. Power = 1000 Watts
Voltage = 120 Volts
To find the current flowing through;
Power = current * voltage
1000 = current * 120
Current = 1000/120
Current = 8.33 Amps
7. Power = 900 Watts
Time = 45 minutes to hours = 45/60 = 0.75 hours
To find the energy consumption;
Energy = power/time
Energy = 900/0.75
Energy = 1200 Joules

beak shape: used to help an animal eat food like tearing apart food or either cracking nuts.
Camouflage: the color or shape of an animals body helps it blend into its envierment.
weebbed feet: help animal's propel themselves through the water with ease. This can help the animal swim faster to
catch prey or escape a predator. Also, if an animal has to swim long distances,

How is your body temperature held constant?
The elasticity of those capillaries plays a central role in our ability to maintain constant body temperatures. When there's too much heat in the body, our capillaries automatically expand and increase the blood flow to the skin, allowing the excess heat to transfer to the air.
