Answer:
About 95 percent of the skin cells in the epidermis are devoted to creating new skin cells in the lower two levels of the epidermis, which then cycle to the top layer to help form the stratum corneum. Eventually the dead cells of the stratum corneum flake off as new keratinocytes move up, and the cycle repeats itself.
Hope this answer is right!!

Please please help!!
Answer:
option 3
Explanation:
A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. A pure bred plant with green spherical shaped seeds is crossed with a pure bred plant with yellow dented shaped seeds. State the phenotype and genotype for the parent plants p1 and p2
Answer:
The correct answer is -
P1: SSyy
p2: ssYY
Explanation:
In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.
It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.

Passive smoking may be banned in cars. Explain
how this may affect the number of cases of
lung cancer. [2]
Answer:
It would decrease the number of lung cancer cases
Explanation:
Many patients with lung cancer don't have to be actively smoking so they can actually get lung cancer by secondhand smoking(passive) especially in cars as the air is polluted and the car is like a small compartment with polluted air( lung cancer occurs over long periods of prolonged exposure especially in children)
Suggest why most plants die very quickly if their roots are cut off
Answer:
because plants are living things, and so if someone cuts you in half, then you're most likley gointnto die pretty quick. HOWEVER.... ur body will still most likley be moving because of adrenaline and left over energy.
Answer:
They wouldn't be able to absorb water and other nutrients from the ground if their roots were cut off.

Which of the following statements is correct regarding engineering maize plants with a herbicide-resistance gene using Agrobacterium-mediated plant transformation?
a. The Ti-plasmid used for this experiment must contain tumor-inducing genes.
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
c. The herbicide-resistance gene is cloned into a region outside of the T-DNA in the Ti-plasmid.
d. A guide RNA is used to transfer T-DNA from Agrobacterium to the plant cell.
e. The whole Ti-plasmid containing the herbicide-resistance gene is inserted into the maize genome after infection with Agrobacterium
Answer:
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
Explanation:
Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.

Describe the biome in which you currently live, or one in which you want to live, or have lived. What are the atmospheric conditions (wind pattern, humidity level, etc), solar intensity, and geographic/oceanographic features that have produced this unique ecosystem
Answer:
Southern Texas
Explanation:
The Wind pattern often is represented by the westerlies, which are the winds that flow in the northern latitude of the world. The humidity level in this zone varies from 10-20%, since we are in the desert we do not have much humidity, the solar intensity is high, often found in the 9-10 uv range, it is not advised to spend more than 10 minutes on direct sun without solar protection. We have the Rio Grande to the south and some spare mountains.
Answer:
Southern Texas
Explanation:
Name three different cells in a leaf that contain chloroplast. Please help
The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS
• the palisade mesophyll
• the spongy mesophyll and
• the stomatal guard cells
The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

Microbes vary in their tolerance of and requirements for oxygen. While obligate aerobes require oxygen to survive, other microbes can be killed by oxygen. H. pylori is considered a microaerophile as it grows best in a low oxygen environments, which is consistent with the environment in the stomach. What type(s) of microbe is/are likely to be found in the following locations of the body
Hi. Unfortunately, you did not submit the parts of the body to which the question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
Microorganisms can be aerobic or anaerobic. Aerobics are those that survive in the presence of oxygen and therefore may be present in parts of the cup that have contact with oxygen. Anaerobic organisms are those that do not survive in the presence of oxygen and therefore can only be present in places in the body that do not come into contact with oxygen.
In this case, to answer your question, you need to identify if the parts of the body, that your question presents, come into contact with oxygen or not. This way it is possible to inform if the microorganisms that these parts of the body have are anaerobic or aerobic.
wich of the following processes takes place during prophase
Answer:
the nuclear envelope dissolves and chromosomes condense. The chromosomes migrate to the center of the cell and align during metaphase. The mitotic spindle fibers attach during metaphase and retract during anaphase, pulling sister chromatids from each chromosome to separate poles of the cell.
