D- Desert

Answers

The best topsoil will be found in the tropical region.

What are tropical regions?

They are regions of the world located within the two tropics - tropic of Capricorn and tropic of Cancer.

The region is characterized by adequate precipitation and relatively warm annual temperature. Thus, there is a high diversity of plants and animal species.

Tropical forests are known as the biodiversity hotspots of the world. This means that the soil is rich enough to support a diverse species of plants as compared to other regions of the world.

How is the soil in the temperate region?

The soil of these forests is very rich in nutrients, mainly due to the natural process of leaf decomposition, which enriches the soil with nutrients. The accumulation of organic matter occurs mainly in the first horizons of the soil, which therefore have a darker color.

With this information, we can conclude that The soil of temperate region It is very rich in nutrients, mainly due to the natural process of decomposition of the leaves.

In a certain population of rats....

Answers

The predicated frequency of homozygous dominant rats at are: 0.11 (Option A). See the explanation below.

What is a homozygous dominant rat?

A homozygous organism has two copies of the same allele for a gene.

If an organism has two copies of the same dominant allele, it is homozygous dominant; if it has two copies of the same recessive gene, it is homozygous recessive.

What is the justification of the above answer?

Note that the total population of rats is: 200

Number of rats with brown fur = 112

The frequency of brown fur rats thus,

112/200

= 0.56

Note that it is also stated that the brown fur rats are dominant in relation to the gray fur rats. Thus, in accordance to Hardy Weinberg's equation, the frequency of the dominant rats is depicted as: p²

Thus:

p²  + 2pq = 0.56

Hence, the frequency of the the Homozygous recessive gray rats is given as:

p² + q² + 2pq = 1

q²  = 1 - 0.56

q² = 0.44

q = 0.663

P = 1-q

= 1 - 0.663

= 0.337

Thus the frequency of the homozygous dominant rats is:

= 0.337²

= 0.1135

≈ 0.11

Therefore the correct answer is A.

Explain whether drivers should be subject to a usage tax if their vehicles contribute more emissions

Answers

The purpose of a carbon tax is to remember the true cost of burning carbon. Those costs are paid by those who suffer from the effects, such as homeowners, farmers, and ultimately the government.

Carbon taxes make sure businesses and consumers pay for the external charges they inflict on society.

How might tax be used to reduce emissions?

Under a carbon tax, the government sets a price that emitters must pay for each ton of conservatory gas emissions they emit.

Companies and consumers will take steps, such as switching fuels or adopting new technologies, to lower their emissions to avoid paying the tax.

The framing effect is a cognitive bias in which the brain makes all the decisions about information depending upon how the information is presented to them. In this, people decide the options which were based on whether the options are presented with positive or negative connotations to them. For examples: the students doing examination.

People tend to avoid the risk when a positive frame is presented to them however they seek the risks when a negative frame is presented to them. Framing effect occurs when the decisions which people make are changed as a result of the way in which the outcomes are described to them.

Huntington’s disease is an autosomal dominant affection. Parental's genotype FF and ff. Cross: FF x ff. F1) 100% Ff, heterozygous individuals (Option D).

What is the Huntington’s disease?

Huntington's disease is caused by a mutation in the gene that codifies the Huntington protein (Htt).

The mutation produces an altered form of the protein leading to the neuron death in certain brain areas.

Huntington's disease characterizes for being,

Hereditary, passing from generation to generation. To express the disease the person must have been born with an altered gene.

     

Autosomal, affecting men and women equally because the mutated gene is located on an autosomal chromosome.

Dominant, meaning that by inheriting only one copy of the altered gene from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy.

Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.

ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some questions.

If two parents are contributing genetic material to their offspring, why don’t the genes and chromosomes double in each generation?

If each parent has two sets of genes and chromosomes, why do their offspring receive only one set from each parent?

Answers

Answer:

1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).

2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.

Design an imaginary food web or describe a real one. Include at least 4 living organisms that interact in your ecosystem.

Answers

The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, beetle, rabbit, frog, eagle, fox, mountainlion, and fungi.

What is the trophic web?

The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.

The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

• The first link corresponds to a producer organism -autotroph-.

• The following links are the consumers -heterotrophs- ⇒ herbivores and carnivores.

• The last links are the decomposers that degrade organic matter from dead organisms.

Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.

Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Example.

To make the trophic web, first, we need to have at least four links.

So first, let us list the organisms we are working with, and then define the position of each of the organisms on the web.

plants,beetle,rabbit,frog,fox,mountain lion, eagle,Fungi

Producer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.

Consumers → heterotroph

Herbivores → These are the animals that feed on any part of the plants → These are the beetle and the rabbit

Carnivores → These are the animals that feed on herbivores → These are the frog, the fox, the eagle, and the mountain lion

Decomposer → detritivorous organisms that take energy from dead matter → Fungi

Trophic web,

Plants directly provide energy to the beetle and the rabbit

Plant >> Beetle and Rabbit

The eagle takes energy from the rabbit and the frog takes energy from the beetle.

Rabbit >> Eagle

Beetle >> Frog

The fox takes energy from the frog and from the rabbit

Frog and rabbit >> Fox

The Fox and the eagle transmit energy to the mountain lion.

Fox and Eagle >> Mountain lion

Fungi takes energy from dead organic matter

Plants, beetle, Rabbit, Fox, Eagle, Mountain lion >> Fungi
