Black fur colour is controlled by a dominant allele, B, and brown fur color by it's recessive allele, b. This characteristic is NOT sex linked. Give the genotypes of the parents and offspring of a cross between a black male and a brown female that produces 1/2 black offspring and 1/2 brown offspring.
Show all steps in working of this problem.
Answer:
What are specialized cells
Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.
What is the dominant allele?The connection between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.
The Cross between parents is Bb x bb
Gametes- B and b
Offsprings- Bb, Bb, bb, bb
The crossing analysis is attached in the image below.
A person needs two copies of a recessive allele, one from each parent, in order for it to result in a recessive phenotype.
Therefore, Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.

Help please and are the ones that already answered to are correct ?
Yes, all of your answers are correct except for number 12. Instead I would say a food chain outlines who eats whom but a food web is all of the food chains in an ecosystem.
Primary consumers are basically herbivores, such as squirrels, rabbits, crickets, etc.
Secondary consumers are carnivores/omnivores, animals that eat other animals such as foxes, snakes, and owls.
Higher order consumers are animals that can eat more things, like humans for example, because we eat animals that are bigger than us like cows but we also eat plants.
Omnivores are animals that eat meat and plants, such as humans and mice because according to your food web, mice also eat meat.
I can’t see the picture very well because it’s blurry, but i think the owl eats some kind of animal that looks like a frog and snakes, so if the owl is removed the frog animal thing and snakes would increase.
for the last question, i would say

Maggots get their energy by breaking down dead and decaying animals. What are maggots? autotrophs producers decomposers heterotrophs.
Food is the source of energy that is used by the organism for the process of metabolism. Maggots are the larva of flies and depend on dead and decaying matters.
Maggots are:
Option C. Decomposers
This type of organism can be explained as:
The organism is classified into different classes according to the nature of its feeding habits.Autotrophs are called the primary producer and break inorganic compounds into organic for energy.Producers are the organism that produces their food by converting solar energy into chemical energy.Decomposers are small-sized organism that lives in soil and breaks the organic compound of dead and decayed bodies.Heterotrophs are organism that depends on other sources and producers for energy.Therefore, maggots are decomposers.

Which mechanism allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries
Answer:
Diffusion.
Explanation:
The mechanism that allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries is simple diffusion.
Simple diffusion is a passive transport mechanism that allows lipid-soluble substances to move across the membranes of endothelial cells in capillaries. This process occurs down a concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for energy expenditure.
The membranes of endothelial cells, which make up the walls of capillaries, are composed of a lipid bilayer. Lipid-soluble substances, such as oxygen, carbon dioxide, steroid hormones, and certain lipid-soluble drugs, can readily diffuse through this lipid bilayer due to their ability to dissolve in and pass through the hydrophobic interior of the membrane.
Unlike lipid-soluble substances, water-soluble substances, such as ions and polar molecules, are unable to passively diffuse through the lipid bilayer. Instead, they rely on specific transport mechanisms such as facilitated diffusion or active transport to cross the endothelial cell membrane.
In the context of capillaries, simple diffusion allows lipid-soluble substances to move from the bloodstream through the endothelial cell membranes and into surrounding tissues or vice versa. This process plays a crucial role in the exchange of gases, nutrients, and waste products between the bloodstream and the tissues.
It is important to note that while simple diffusion allows for the passage of lipid-soluble substances, the movement of these substances can also be influenced by factors such as concentration gradients, molecular size, solubility, and the presence of transport proteins. However, the primary mechanism by which lipid-soluble substances traverse the endothelial cell membranes of capillaries is through simple diffusion.

The first reaction of the body to a cut is to restore the continuity ?
Explanation:
First,blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.The platelets then release chemicals called Cytokines into your blood stream.Cytokines attract the attention of certain cells to start healing your cut.
When the skin injured,our body sets into motion an automatic series of events,often reffered to as the " cascade of healing",in order to repair the injured tissues.The cascade of healing is divided into four overlapping phases:Hemostasis,Inflammatory,Poliferative,and Maturation.
