Your skin cells have 46 chromosomes. After they complete the cell cycle, how many chromosomes will be in the daughter cells? Explain.
Answer:
46
Explanation:
The skin cells with 46 chromosomes will each produce daughter cells with 46 chromosomes after they complete the cell cycle.
The skin cell is a vegetative cell that can only divide through mitosis. Mitosis is also referred to as equational division during which a cell produces two daughter cells that are both genetically and phenotypically similar to the parent cell.
During the cell division, at the anaphase stage to be precise, the chromosomes are separated into sister chromatids and sister chromatids of the same chromosomes move in the opposite direction to the poles of the cell before the cytoplasm of the mother cell divides to produce two independent daughter cells. Each chromatid in the new daughter cells then goes ahead to become a complete chromosome with two sister chromatids.
Hence, at the end of the cycle, each daughter cell ends up having the same 46 chromosomes as the parent cells.

Tay Sachs disease is an autosomal recessive disorder involving the hexoaminidase gene. What type of mutation occurs in this gene?
Tay-Sachs disease is caused by mutations in the HEXA gene and inheritance is autosomal recessive . The HEXA gene gives the body instructions to make part of the beta-hexosaminidase A enzyme, which is needed to break down a substance called GM2 ganglioside.

These limbs provide evidence of common ancestry because they -
Answer
A have the same basic structure
B pedom the same function
С
are the same size
Dare parts of mammals
Answer:
The answer is A
Explanation:
All the the different limbs all have an upper arm bone which is the humerus and two forearm bones which are the ulna and the radius.
The limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.
What is a common ancestor?A common ancestor may be defined as an ancestral organism that is significantly shared by two or more descendent lineages. In a more simple term, an ancestor that they have in common. These ancestors follow each taxon's lineage back in time until all the lineages meet up.
A Common Ancestor is a lineage that undergoes cladogenesis, that is, branching evolution, such that more than one species can trace its ancestry back to the common ancestor or, more accurately, to multiple common ancestors.
Therefore, the limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.

How do metamorphic rocks work?
Answer: Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock. rocks that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure.

How does leaf structure allow for exchange of gases (O2 and CO2). Select 3 options.
Stomata (pores) let gases pass in and out.
Leaf is flat and thin = large surface area
The leaf has got Chloroplasts.
The Spongy Mesophyll layer has lots of space for gases to diffuse.
Answer:
Explanation:
Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.

The table below shows the percentages of bases in a DNA sample. How much Guanine (G) should you expect to find in the sample?
Answer:
17%
Explanation:
guanine is cooped
with cytosine
Using Chargaff's rule, the percentage of Guanine(G) in the sample is always equal to the percentage of Cytosine. Hence, the percentage of Guanine which is expected to be found in the sample ls 17%.
From the table attached :
Thymine = 33%Cytosine = 17%According to Chargaff ; the percentage of Cytosine equals the percentage of Guanine :
Guanine = Cytosine = 17%.
Percentage of Thymine equals the percentage of Adenine :
Adenine = Thymine = 33%Therefore, the amount of Guanine which is expected to be found in the sample is 17%

What are the 5 main functions of soil? List and describe each
Soil covers the surface of the Earth and is a valuable ecosystem. Soil is made up of minerals, nutrients, water, air, organic matter and microorganisms. Because of its makeup, soil has a variety of uses in a variety of industries.
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.
Pottery
Clay soil is used in making ceramics, or pottery. When water is added to clay soil, it can be used to create the ceramics. Once formed, you can leave it to dry and it will retain its shape. Any type of ceramic can be created with the clay soil, such as a vase, bowl, cup or sculpture.
Medicine
Soil is commonly used in antibiotics. Microbes created in the soil are harmful to bacteria, which is why soil is used in medicine. Medicines created by soil include skin ointments, tuberculosis drugs and anti-tumor drugs.
Beauty Products
Some beauty products are made with soil. Commonly used beauty products where used soil is used in the production include blush and foundation. Soil rich in clay can also be used in facial masks and toothpastes.
The main function of the soil is to serve as a seat, facilitate the permeability and circulation of water and air, being important for plant life.
What is soil?It is the layer that covers the most superficial part of the planet and it is where plants grow and animals live.
Functions of soilBiomass production.It supplies water, air, and nutrients to plants, provides food, energy, raw materials, and natural traits.
Hydrological function.It intervenes in the regulation of infiltration, storage and flow of surface and subsurface water and its quality.
Environmental function of filtering, storage and transformation.Filtering, pH buffering, retention of hazardous waste compounds and polluting discharges, etc.
Biological habitat and gene pool.Reserve of genes of animals and plants essential for the maintenance of biodiversity.
Wheater regulating function.Sink of greenhouse gases and effects on the global energy balance and the global hydrological cycle.
Therefore, we can conclude that soils acts as a filter, buffer medium and storage of water, air, nutrients and chemical products or discharges.
