The syntenic genes B and T are linked. A cross between two parents, with genotypes BBtt and bbTT, produces F1 progeny with the BbTt genotype. What are the possible arrangements of alleles on the F1 progeny's chromosomes

Answer: Deforestation also degrades soil quality and is a major cause of the world's rapid desertification. Such weather patterns and environmental changes contribute to the plummeting of the agricultural production. Humans are hit by food shortage due to the low agricultural produce. Anyone can make a difference at some level by contributing to the fight to save forests and wildlife by making informed choices on a daily basis. Using ecofriendly products, eating sustainable foods, recycling more, and conserving water and energy can help to lead towards zero deforestation.

Answer:

Explanation: 1+1

Answer:

The answer is the sun.

Explanation:

Level a represents the producers which you can tell, by their name, that they make their food. Producers are mainly comprised of the plants of our world. They get their energy from the sun and through photosynthesis, they turn it into energy.

By the way, B would be primary consumers which are the herbivores, C are the secondary consumers which include us people, and D are the decomposers, which include worms.

Level A represents the producers which make their own food and are mainly comprised of the plants of our world. They gain energy from the sun and through the process of photosynthesis.

The energy for use by organisms in level A originally comes from sun. Thus the correct option is A.

The process through which green plants and some other organisms use sunlight to make foods from carbon dioxide and water. Photosynthesis in plants generally involves the green colour pigment chlorophyll and generates oxygen as a byproduct.

Whereas, B would be primary consumers which are the herbivores, C are the secondary consumers that include omnivorous, and D are the decomposers, which include worms.

Answer:

in the left direction.

Explanation:

since the force applied from the right is greater than the left and the force applied from below is opposite, which leaves no change in displacement.

therefore, the object would move to the left direction.

Explanation:

In an experiment, the control group is the group that does not receive any experimental treatment. The control groups are kept in the same condition as the experimental group except the variable being tested (independent variable).

In this question involving an experiment to determine the effects of antibiotics on the treatment of pneumonia in mice. Two groups of mice were employed. One of the groups (group A) received no antibiotic while the other group (group B) received 10 mg/kg of antibiotics. This means that GROUP A is the CONTROL GROUP of this experiment.

Answer:

Difference in chromosome number.

Explanation:

The reproductive cells from an apple tree and a banana tree never combine to form an offspring because of the difference of species. There is different number of chromosomes in the both apple and banana tree. There are 17 number of chromosomes in apple whereas 33 number of chromosomes in banana tree so due to this difference in the chromosome number apple and banana tree can produce offspring due to combination.

The process of formation of new offspring from the parents is called reproduction. Reproduction help to ensure the continuity of species generation after generation. There are two types of reproduction, these are as follows:-

Reproduction required the gametes of the same species for fusion. The mating of the two gametes is known as fertilization.

According to the question, the apple tree and a banana tree never combine to form offspring because of the gamete difference, These gametes are from different species.

Hence, they cannot reproduce.

The correct statement is that the outer planets are further from one another than the inner planets. So the correct option is D.

There are eight planets in our solar system that are classified according to their distance from the sun.

The planets closest in distance to the sun are called the inner planets. The first four planets of the solar system are classified as the inner planets. These are Mercury, Venus, Earth, and Mars.

The rest of the four planets of the solar system are farther in distance from the sun. They are called the outer planets. These are Jupiter, Saturn, Uranus, and Neptune.

The outer planets are much bigger than the inner planets and make up for 99 percent of the mass of all celestial bodies that revolve around the sun.

The outer planets are mainly composed of gases and are called gas giants or jovian planets. The distance of outer planets between one another is much more than the distance of inner planets between one another.

Therefore, the correct option is D.

Answer:

I believe the answer is B. Vomiting and Fever.

Explanation:

This answer makes the most sense as spoiled food can lead to sickness, which can lead to vomiting and fever.

Answer:

The answer is below

Explanation:

The half life of a substance is the time required by that substance to reduce to half of its initial value. The half life is calculated using the formula:

[tex]N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\where\ N(t)=quantity\ of\ substance \ remaining, N_o=initial\ quantity\\of\ substance, t=time\ and \ t_\frac{1}{2}=half\ life\ of\ substance[/tex]

Given that t = 87 years, half life = 29 years, therefore the quantity of strontium-90 left is:

[tex]N(t)=N_o(\frac{1}{2} )^\frac{87}{29} \\\\N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\N(t)=N_o(\frac{1}{2} )^3\\\\N(t)=\frac{1}{8} N_o[/tex]

That is one-eight of Strontium 90 would be left after 87 years
