The earth , the sun , and the seven other planets that are in orbit around the sun are part of the solar system. How does the size of the solar system compare with the size of the milky way galaxy ?

Answers

Answer:

Size of milky way galaxy is very large than our solar system.

Explanation:

The size of the solar system is much smaller than the size of the milky way galaxy because our solar system is a part of milky way galaxy. The radius of our solar system is 4.545 billion km while on the other hand, the radius of the milky way galaxy is 52,850 light years which is very very large than the radius of our solar system. Milky way galaxy has 100–400 billion planets while in our solar system has only eight planets.

2. Tim and Stephanie are devastated when the

would have gotten it from him. Is Tim ce
genotypes must be in order for neither of them have the disease but have a son who does​

Answers

Answer:

Explanation:

Tim and Stephanie are devastated when they find out their newborn son has hemophilia- sex-linked recessive disease. Tim is shocked because he doesn’t have hemophilia, and figured if his son has it he would have gotten it from him. Is Tim correct in his thinking? Explain. Also explain what their genotypes must be in order for neither parents to have the disease but their son does. Create a Punnett square, and indicate the mother's and father's genotype.

First of all, the thinking of Tim is wrong. Hemophilia is X-linked and a male (XY) child always inherits his X chromosome from his mother. Hence, the newborn son of Tim must have inherited the allele for the disease from Stephanie.

Now, neither Tim nor Stephanie showed any symptom of hemophilia. It could only mean that Tim is totally free of the hemophilic allele while Stephanie is a carrier for it. Because a man has just one X chromosome, he can either be totally free of the abnormality or affected by it, no in-between. A woman has two X chromosomes, hence, she can be totally free, a carrier, or affected for the disease. Assuming the allele for hemophilia to be h, Tim's genotype would, therefore, be [tex]X^HY[/tex] while that of his wife would be [tex]X^HX^h[/tex] .

The Punnet's square analysis of the cross between Tim and Stephanie is indicated in the attached image.

How do most primary producers make their own food? *

Answers

Explanation:

most primary producers are plants and they produce food by photosynthesis. In photosynthesis they use carbon dioxide, water and light (most times sunlight) to make glucose and oxygen. the glucose is their food and oxygen is the waste product and is given out.

Most primary producers make their own food through the process of photosynthesis.

What is photosynthesis?

Photosynthesis is a biochemical process that occurs in the chloroplasts of plant cells (as well as in certain algae and some bacteria) and uses energy from sunlight to convert carbon dioxide and water into glucose (a simple sugar) and oxygen.

The chlorophyll pigment in chloroplasts captures light energy, which is then used to drive the synthesis of glucose through a series of chemical reactions.

This process allows primary producers to produce organic compounds and serve as the foundation of the food chain by converting sunlight energy into chemical energy that other organisms can consume.

Answers

Answer:

The basic building blocks of proteins are called amino acids. In proteins, amino acids are arranged into a linear molecule called a polypeptide chain. Some proteins only consist of a single polypeptide chain while more complex proteins are made out of multiple polypeptide chains bonded together.

Explanation:Proteins are formed out of long linear molecules of amino acids called polypeptide chains. The identity and function of a protein are determined by its sequence of amino acids and the 3-D structure of its polypeptide chains. Amino acids are stored in DNA in the form of sequences of nucleotide bases.

B: Multiple gene mutations

Explanation:

Mutations can be very small changes, affecting only a few nucleotides or they can be very large, leading to major changes in the structure of chromosomes. Both small and large mutations can affect the behavior of cells. Combinations of mutations in important genes can lead to the development of cancer.

Uncontrolled cell growth phrase best describes the Cancer. So, the correct option is (C).

What is Cancer?

Cancer is a disease which caused when the cells divide uncontrollably and it is spread into surrounding tissues. Cells which are divided uncontrollably they are abnormal in nature and also spread to different parts of the body. These cells may form in the lumps of tissues known as Tumors. They are of two types - Cancerous  and Non-Cancerous (benign).

Cancerous tumors spread to the nearby tissues or invade into it. It can travel to different places in the body to form new tumor which is called metastasis. Cancerous tumors  are also called malignant tumors. Mots of the cancers occur from the solid tumor but in case of blood cancer, it is not.

It is mainly caused by the alteration of DNA. Genetic changes that cause cancer can occur because

Some errors which occur when the cells divide. Damage to DNA which caused by harmful substances in the environment, such as the chemicals in tobacco, smoke, etc.It can be inherited from the parents.

What is terrestrial species?

An animal or plant that lives on land or in the ground, as opposed to the sea, trees, or the air, is said to be terrestrial. There are occasionally aquatic and terrestrial animals seen sleeping next to each other under a loose stone.

These animals can run quickly because the majority of them have legs. They must move quickly to capture their prey or avoid being an animal's next meal (predators). Komodo dragons and red-tailed boas have so many differences, even though they share a common ancestor.

Therefore, Order Urodela has amphibian with aquatic and terrestrial species with very flexible bodies, has a tail, and retains its juvenile features throughout its life.
