HELP AND ILL PUT U IN BRAINLIEST

Answers

Answer:

By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.

Explanation:

The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.

Parental generation:

Plant with purple flowers PP Plant with white flowers pp

Cross: PP X pp

Punnett Square :

Alleles P P

p Pp Pp

Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.

According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.

What is the anatomy of a leaf

Answers

Answer:

Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole.

Which statement best compares the amount of fossil fuels formed each year to the amount used each year? The amount of fossil fuels formed is exactly the same as the amount used. The amount of fossil fuels formed is approximately the same as the amount used. The amount of fossil fuels formed is much less than the amount used. The amount of fossil fuels formed is greater than the amount used.

Answers

Answer:

The amount of fossil fuels formed is much less than the amount used.

Explanation:

Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.

One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

People who have Tay-Sachs disease cannot metabolize some lipids effectively. Tay-Sachs is a recessive disorder. A student used a Punnet Square to determine the probability of offspring inheriting the disease. The results from a Punnet Square are 25% TT, 50% Tt, and 25% tt.

Which conclusion can be made regarding the phenotype of the parents based on these results?

The parents must be TT, Tt

The parents must be Tt, tt

The parents must be TT, tt

The parents must be Tt, Tt

Answers

Answer:

The parents must be Tt, Tt

Explanation:

Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:

T t

T TT Tt

t Tt tt

We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).

This means that the parents must be Tt, Tt.

What types of solid waste do you produce in your home ?what could be done to each type and what goes to the disposal site or dumpsite

Answers

Answer:

Types of solid watse we produce in your home is plastic cups, metal forks and spoons, and also glass plates. We could recycle these items, so they can become other new items when we are finished.

Solid waste are described as abandoned waste materials resulting from human and chemical activities. Solid wastes could include used plastic materials, rubber, metals, glass and other materials classed as useless.

In Homes, solid wastes usually include used plastic, shattered glass, metal objects and so on.

Plastic wastes and metals could be recycled and refined to make rubber and aluminium spare parts, hence, serving as raw materials.

Therefore, since solid materials take very long to Decay, hence recycling of the waste and their use in organic products are always good means of disposal.

Answer:

It is Running, jumping, and biking are controlled by the cerebrum.

Explanation:

I had question this on my test last week

Answer: Organs are more complex than the tissues they are made from.

Explanation:

A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not? A No, because the arrangement of atoms is different in the reactants and products. B Yes, because the reactants and products are made of atoms of the same elements. C Yes, because the number of atoms of each element is the same on both sides of the equation. D No, because the total number of atoms in products is greater than the total number of atoms in reactants.

Answers

C. Yes, because the number of atoms of each element is the same on both sides of the equation.

Due to the law of conservation of mass, any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.
