2. Tim and Stephanie are devastated when the
recessive disease. Tim is shocked because
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
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.

Explanation:
The device used to determine the probable outcome of genetic crosses, is called a punnet square.
We know that genes are units of inheritance located in the chromosomes and control different traits in living things. Genes mostly occur in pairs. The pairs of genes are called alleles. The observed traits of an organism is called its phenotype and it depends on the combination of genes.
A punnet square as shown is used to determine the most probable outcome of the crossing of genes in individual organisms.

Why are plants, but not animals, thought to be an important factor in classifying a land biome?
Answer:
becuase plants make up surrounding areas, if you see no plants and soil with no fertilization from plants it is most likely a desert, and a place with tall and thick plants is most likely a forest
Answer:
Explanation: Because the biome must support the plant since the grow a plant you must have good temperature the constant rainfall and the soil, that is why plants are the most important factor since its chooses what plant can survive in that biome.

Energy makes it all happen. The Sun radiates huge amounts of energy. Only a small portion of that energy hits the Earth, but it is enough to light our days, heat our air and land, and create weather systems over the oceans. Most of the energy you will learn about comes from the Sun.

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

how does the law of conservation of energy apple to virbatioin
Answer:
As objects move around over time, the energy associated with them—e.g., kinetic, gravitational potential, heat—might change forms, but if energy is conserved, then the total will remain the same. Conservation of energy applies only to isolated systems.

How do most primary producers make their own food? *
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.

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 ?
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.

The two reactions shown below represent processes that occur in living organisms.
Carbon dioxide + Water + Sunlight →Sugar + Oxygen
Sugar + Oxygen
Water + Carbon dioxide + Energy
Which of the following statements is correct about the two reactions?
O Oxygen (02) is used to release energy during photosynthesis
O Carbon dioxide (C02) is used to release energy during photosynthesis.
O Sugar (C6H1206) is broken down to release energy during cell respiration.
O Water (H20) is broken down to release energy during cell respiration.
Answer:
C. Sugar is broken down to release energy during cell respiration
Explanation:
In the picture sugar is one of the inputs of cellular respiration and energy is the output of it. Meaning sugar turns into energy.
The statement which is correct about the two given reactions is that the sugar (C6H1206) is broken down to release energy during cellular respiration. Thus, the correct option for this question is C.
What is Cellular respiration?Cellular respiration may be defined as a chemical process through which oxygen is significantly utilized in order to make energy from carbohydrates (sugars). Through this process, living organisms break down glucose into a form that the cell can use as energy.
With the help of the given reactions, oxygen is the byproduct of the photosynthesis reaction along with the main product glucose. While carbon dioxide is the reactant of the photosynthesis reaction and the product of cellular respiration.
In the process of cellular respiration, Sugar (C6H1206) is broken down to release energy along with carbon dioxide and water.
Therefore, the correct option for this question is C.
