Answer:
A genome is composed of one or more DNA molecules, each organized as a chromosome.
Prokaryotic genomes are mostly single circular chromosomes.
Eukaryotic genomes contain nuclear and organellar components. The nuclear complement of the genome consists of one or two sets of linear chromosomes.
Explanation:
True or False: The chromosomes in sex cells have homologous pairs.
Answer:
True
Explanation:
Answer:
True
Explanation:
In body cells, most chromosomes are found in pairs that have the same structure and size. These homologous chromosomes carry the same genes. A homologous chromosomes pair may have different versions of the genes they carry. Once chromosome pair is made up of sex chromosomes.

HELP PLEASEEEEEEEEEEE
Answer:
2. Dominant 3. Recessive 4. H---zygous 5. Heterozygous 6. Hybrid 7. Purebred
Explanation:
2
Upper case letters always represent dominant alleles.
3
Lower case letters always represent recessive alleles.
4
"H---" means same, if you see too upper case letters or two lower case letters it's H---zygous.
5
"Hetero" means different, if you see one upper case and one lower case or two different letters, it's Heterozygous.
6
A hybrid is something with pieces of two different things, like hybrid cars that get energy from gas and heat.
7
I can't think of a way to memorize the word "purebred". Sorry.

What would you expect to happen if your blood sugar was 120mg/100mg?
Answer:
The 120 miligram per 100 milliliter of the sugar suggests that the blood is hyperglycemic.
Explanation:
the hyperglycemia is the condition, in which the blood sugar level increases than the normal blood sugar levels. The main cause of the insulin is decreased function of the insulin hormone. The condition, in which the insulin is not working properly and is unable to metabolise the sugar (glucose) present in the blood is known as Diabetes.
So, the given case can be a result of diabetes.

Write function of snakes hard scales
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"function of snakes"
Snakes are elongated,legless,carnivorous reptile of the suborder serpents.Like all other squamates,snakes are exothermic,amniotic vertebrates covered in over applying scales.Many species of snakes have skulls with several more joints than their lizard ancestors,enabling them to swallow prey much larger than their heads with their highly mobile jaws.To accommodate their narrow bodies,snakes,oared organ appear one in front of other instead of side by side,and most have only one functional lungs.Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.Legless lizard have eyelid and external ear.
A scale protect the body of the snakes,aids it in locomotion,allows moisture to be retained within,alters the surface characteristics such as roughness to aid in camouflage,and in prey capture (such as Acrochordus).
Snake scale originates from the epidermis.The integument of the snakes in covered with two primary scale type,both originating from the epidermis.Small scale over the dorsum and lateral surface of the snake.Whereas larger scales cover the vent rum.

what is energy? HEJSIDNCIF
Answer:
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

discuss the stages of the cell cycle mechanism that regulate it and how this cycle is related to the growth and maintenance of organisms
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Cyclins regulate the cell cycle only when they are tightly bound to Cdks. To be fully active, the Cdk/cyclin complex must also be phosphorylated in specific locations. Like all kinases, Cdks are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.

A person who is heterozygous for hair type will have a phenotype of wavy hair. If one parent has wavy hair and the other parent has curly hair, what percentage of their children will have wavy hair? A 25% ® 50% 75% 100% A
Answer:
C) 50%
Explanation:
If wavy hair is heterozygous then wavy is dominent and curly is recessive. So the alles for wavy would be Ww and for curly it would be ww. Put that on a punnet square and it is 50-50

How does wet soil differ from dry soil in its ability to absorb heat?(1 point)
A. Wet soil absorbs heat more slowly, due to water's low evaporation point.
B. Wet soil absorbs heat more quickly, due to water's low evaporation point.
C. Wet soil absorbs heat more quickly, due to water's high heat capacity.
D. Wet soil absorbs heat more slowly, due to water's high heat capacity.
Answer:
D.) Wet soil absorbs heat more slowly, due to water's high heat capacity.
Explanation:
Just took the quiz
The mixtures of the minerals, organisms, nutrients and compounds are called soil. Due to water's high heat capacity heat is absorbed slowly by the wet soil.
What are the types of soil and heat capacity?The type of soil that is filled with water molecules in its pores and lacks air in it are wet soil, on the other hand, the soil that has no moisture content in it is called dry soil.
When there is a variation in the temperature then the ability of the soil or substance to absorb heat is called heat capacity.
Water present in the pores of the wet soil has more heat capacity and therefore the heat absorbed by the wet soil is slower than the dry soil.
Therefore, option D. wet soil is slower in absorbing heat.

If a 4 kg object is moving 5 m/s, how much kinetic energy does it have?
Answer:
K.E = 50 J
Explanation:
Given data:
Mass of object = 4 Kg
Speed of object = 5 m/s
K.E = ?
Solution:
Formula:
K.E = 1/2mv²
by putting values,
K.E = 1/2 × 4 Kg × ( 5m/s)²
K.E = 1/2 × 4 Kg ×25 m²/s²
K.E = 50 J (Kgm²/s² = J)
