A roan cow is crossed with a red cow. What percent of the offspring will be roan?

Answers

Answer:

Red cows have a dominant red allele and white cows have a dominant white allele. When a red cow mates with a white bull, they can have offspring that have the color that is called Roan which is a red and white spotted appearance. This is an example of co-dominance

Explanation:

CORRECT ME IF I AM WRONG

If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.

CO-DOMINANCE:A roan cow phenotype is a product of co-dominance between red (R) and white (W) alleles. This means that a roan cow will have a RW genotype.

If a roan cow is crossed with a red cow i.e. RW × RR, the gametes produced by each cow is as follows:

RW - R and WRR - R and R

Using a punnet square, the following offsprings of cow will be produced: 2RR, and 2RW.

This means that the percentage of roan cows in the offspring will be 50% i.e. ½ × 100 = 50%.

Therefore, If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.

How is water traveling underground to lost Lake?

Answers

Answer: Water becomes the part of the aquifer.

Explanation:

Water from rain, snow fall, river, lakes, ponds, ocean, irrigation field, and from other sources become the part of the ground water or aquifer. The water seep into the soil or rocks and deposited as reservoir of water underground. The underground water when exposed to the surface can become the part of the lost lake or any other water body. Thus the source of lost lake can be determined this way by tracking the distance covered by the ground water.

In an experiment determining the effects of antibiotics on the treatment of pneumonia in mice, two groups of mice with pneumonia are compared. One group, group A, receives no antibiotic, and the other group, group B, receives 10 mg/kg of body weight of a new antibiotic. Besides the administration of the antibiotic, there are no differences between the two groups of mice. What is the purpose of group A

Answers

Answer:

Group A is the control of the experiment

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.

What is the greatest threat humans pose to biodiversity?

Answers

Answer:

Explanation:

What is biodiversity loss?

The term "biodiversity loss" describes the decline in biodiversity brought on by the extinction or relocating of species. Some people might not consider the extinction of a certain species to be significant, especially if it is not a charismatic species such as the Bengal tiger or the humpback dolphin.

However, according to estimates from scientists, the present pace of species extinctions is several times higher than the background, or average, rate seen throughout Earth's history. Within our lifetimes, this amounts to the extinction of tens of thousands of species.

The breakdown of ecosystems is anticipated to have drastic repercussions on human welfare. Because of the intricate relationships between species, a loss of biodiversity may have a ripple effect on ecosystems.

One species' extinction, for instance, may result in the extermination of another. Scientists evaluate which species are in danger of extinction as well as the state of the ecosystems to gauge the loss of biodiversity.

Therefore, the way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.

A __________ is an example of a signal molecule that can bind to an intracellular receptor and thereby cause a gene to be turned on or off. a protein b glyceride c nucleic acid d steroid e carbohydrate

Answers

Answer:

D. steroid

Explanation:

Intracellular receptors are a type of receptors located inside the cell, specifically in the cytoplasm or nucleus. When intracellular receptors are activated by ligands called SIGNALLING MOLECULES, they change shape and regulate genetic expression in the nucleus i.e. they induce turning on and off in a gene.

However, signalling molecules that activate intracellular receptors are usually hydrophobic hormones because they need to easily diffuse through the cell membrane and bind to the receptors located internally. Example of these hydrophobic signal molecules are STEROIDS.

The changes over time in the inherited traits of a type of organism are ____.
A) growth
B) biogenesis
C) spontaneous generation
OD) evolution

Answers

The changes over time in the inherited traits of a type of organism are known as evolution of the species. Thus, the correct option is D.

What is Evolution?

Evolution is change in the heritable characteristics of biological populations which are taking place over the successive generations. These characteristics are the expressions of different genes, which are passed on from the parents generation to their offspring during the time of reproduction.

Variation in the genetic material tends to exist within any given population as a result of the genetic mutations and recombination. Evolution in a species occurs when the evolutionary processes such as natural selection and genetic drift act on this variation in species, resulting in certain characteristics which are becoming more common or more rare within a population than other traits.

Therefore, the correct option is D.

So, she also multiplied the original value for green paint by 5 to get the new value for green paint. There are multiplicative relationships, relationships related to multiplication, in a ratio table. To get from values for green and black in one ratio to values for green and black in another ratio, we can multiply both the initial values by the same number. For example, to get from the ratio 3:2 to the ratio 6:4, we multiply both the 3 and 2 by 2. And to get from the ratio 3:2 to the ratio 15:10, we multiply both the 3 and 2 by 5.Sometimes, there are also relationships related to addition, called additive relationships, in a ratio table. To get from one value for green to another value for green, we can add 3. To get from one value for black to another value for black, we can add 2. When using the multiplicative relationship to find equivalent ratios, we can multiply both columns by the same number. But when using the additive relationship, we cannot add the same number to both columns.A cookie mixture requires 3 teaspoons of sugar for every 4 teaspoons of salt. You want to triple the mixture.
