Based on the Nebular theory, which of these is a step in the formation of the center of a new planetary system?
A. evaporation of condensed gases due to heat
B. combination of condensed gases due to gravity
C. contraction of condensed gases due to nuclear fission
D. expansion of condensed gases due to nuclear fission

Answers

Answer 1

Answer:

The answer is the evaporation of water. As the gas begins to collapse, thermonuclear fusion as a result of the immense gravity at the center of the cloud results in the generation of immense heat and radiation that turns solids and liquid into gaseous form, close to the center of the cloud.

Explanation:

This resulted in the nuclear fusion of gases and dust to create the sun and planets at the outer flattened portion of the disk." The sun forms in the center of the cloud since the gravitation effect that drives thermonuclear fusion are strongest in this region. Planets form in the outer regions of the accretion disks where matter attract each other into clumps and gain even more gravitational pull to yank even more matter.

Hope this helps.

Answer 2

Answer:

A: evaporation of condensed gases due to heat.

Explanation:

Here are the 6 steps:

Nebula, protosun forming, spinning planetary disk, protoplanets forming,

Shock waves from a nearby supernova explosion.

It also begins to flatten.

Protosun.

When the gravitational forces begin to fuse hydrogen into helium (fusion)

Protoplanets.

Inner protoplanets - most of their lightweight gases are boiled away

The last step is the answer.

what is produced by mitosis?

Answers

When a parent cell splits to create two identical daughter cells, the process of the nuclear division known as mitosis takes place in eukaryotic cells.

What is meant by mitosis?

DNA, a molecule found on chromosomes, is the genetic information carrier. They are linearly arranged genes that are present in couples in the cell's nucleus. Genes also are arranged in pairs, and each pair produces a coding that results in the production of a distinct protein.

Mitosis is a sort of cell division that makes sure each new daughter cell formed when a cell splits possess the same genomic structure.

Two cells referred to known as daughter cells are created during mitosis. Any newly formed daughter cells must have genetic material that is similar to that of the parent cell, and the number of chromosomes must stay constant.

Therefore two identical daughter cells are produced as a result of mitosis.

why are owls considered keystone predator

Answers

Explanation:

Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers. 

owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.

Answer:

the owl is a keystone species, as many other birds. and it gives them the nutrients they need when they eat the bird and it mangeges the population of the other species:)

In Figure 30-4, which structure represents unsaturated fat? Which structure represents saturated fat? At room temperature, what state is each type of fat?
State whether each type of fat is associated with heart problems. Give an example of each type of fat.

Answers

The structure on the right is saturated while the structure on the left is unsaturated (presence of double bond). At room temperature the saturated fat will be solid and the unsaturated fat will be liquid.

High consumption levels of saturated fats are associated with heart problems. Consumption of high levels of saturated fats can raise your cholesterol levels and increase risk of heart disease.

Unsaturated fats are not associated with heart problems.

An example of saturated fat would be the fat found on red meat. An example of unsaturated fat would be the fat found in nuts, avocados, etc.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?

Answers

Answer:

This question is incomplete, the complete question is as follows:

- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.

What percentage of offspring are expected to be chestnut?

The answer is 0%

Explanation:

This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.

According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;

BB - B only

bb - b only

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

Bb, Bb, Bb, Bb

All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0%  of offspring are expected to be chestnut.

It goes through a series of "Events" I'll talk you through them lol.

Explanation:

See, when you eat something it goes down the esophagus and into the stomach, then to your small and large intestine. While it slowly travels through your intestines, your body is slowly taking the nutrients from that piece of food, which makes the food turn into a different color, since all the nutrients is taken out of the food, then the body no longer needs that food. Then it disposes from the body!
