Your best friend is concerned about a mole on her arm. Knowing that you are taking a biology class she comes to you and asks for your opinion. You take a sample of her mole and view it under a microscope. While counting a selection of 300 cells, you notice that 87 cells are actively undergoing mitosis. Should your friend be concerned?

Answers

Answer 1
mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. if they do not align correctly, they cannot move individually to opposite poles in the later phases of mitosis, and the result will be one cell with extra chromosomes and a daughter cell with missing chromosomes. These mutations can lead to harmful results such as cell death, organic disease or cancer.
Answer 2

Answer:

She should consult a dermatologist immediately.

Explanation:

When doing preemptive diagnosis of a mole, one should compute the Mitotic Rate (MR) - and the MR reported in the question is way above the highest category "greater than 4 per square millimeter" (to compare. there's around 2000 cells per sqmm of skin, so we're at over 500 per square millimeter).

Answers

Answer:

FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy. ... Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory.Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. 8.arrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel.All the arrows in a combined form are used to show the biogeochemical cycle or the carbon cycle. In this cycle, carbon is cycled between the biotic and abiotic component of the biome. In any biogeochemical cycle, mas and energy are always conserved.

o They protect the plant from pests
o They are involved in plant reproduction
They work together to regulate water loss and gas exchange.
o They regulate the amount of water that enters the plant for cellular respiration

Answers

Answer:

They work together to regulate water loss and gas exchange.

They work together to regulate the loss of water and exchange of gases.

Stomata and guard cells

The tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.

The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.

Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.

Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

Curly hair (C) is dominant where straight hair (c) is recessive. If a person who is CC were to have children with a person who is cc, could it be possible for them to have a child with straight hair?

a
yes
b
no

Answers

Answer:

No, it would not be possible to have a child with straight hair.

Explanation:

The Punnett cross would be CC x cc, so all the offspring would be Cc. Since straight hair is only cc, the kids would not have straight hair.

Awnser:

yes, it is possible :)

Explanation:

Their children would would have the dominant trait, curly hair, and the recessive straight hair gene hidden in their dna. If there was a chance that one of their curly haired children met with a cc-partner with straight hair, then they would have a 1 in 2 chance. Even with a Cc-partner, there would be a 1 in 4 chance of the straight hair trait "skipping a generation".

Como resultado del proceso de la fotosíntesis se elimina a través de los estomas a La glucosa b) El oxígeno. C) El dióxido de carbono d ) Oxígeno y dióxido de carbono

Answers

Answer:

Como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.

Explanation:

La fotosíntesis es un proceso metabólico que llevan a cabo determinadas células de organismos autótrofos, es decir, aquellas que tienen la capacidad de producir su propio alimento, como las plantas. Con este proceso, las plantas captan la energía de la luz solar y la transforman en energía química, para producir materia orgánica a través de materia inorgánica.

Los procesos que llevan a cabo las plantas en la fotosíntesis se llevan a cabo en 2 etapas: en la primera etapa las plantas absorben el agua del suelo a través de las raíces. A través de sus tallos lo transportan hasta sus hojas. En estos se encuentra el pigmento llamado clorofila, que además de darle a la hoja el color verde, capta la luz solar y rompe la molécula de agua (H₂O), separando el hidrógeno (H) del oxígeno (O₂). En esta etapa se almacena energía y se libera oxígeno al medio ambiente.

La otra etapa es capturar dióxido de carbono. Esto proporciona los átomos de carbono y oxígeno que, junto con el hidrógeno y la energía almacenada, formarán la molécula de glucosa.

Entonces, los estomas son poros en la superficie de las plantas, encontrándose mayoritariamente en las hojas y en menor medida en los tallos y otros órganos. En ellas transcurre el intercambio gaseoso mecánico, es decir que en este lugar sale el oxígeno y entra dióxido de carbono en la fotosíntesis.

Por lo que, como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.

Explanation:

Embryonic development is the formation of organisms that starts from the process of fertilization. The stages of development represent mitosis.

What is mitosis?

Mitosis is a part of the cell cycle, that produces two identical nuclei and daughter cells from the division of the cell and replication of the parent cell.

From the diploid parent cell, two diploid daughter cells are produced in mitosis. This process is the first and the initial stage of embryonic development that initiates the growth and development of the embryo from the parent cell.

A) No, the causes of body cell mutations are outside the body and cannot alter DNA.

B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.

C) Yes, these body cell mutations lead to mutations in the gametes.

D) No, the mutations cannot be passed to offspring and only affect the individual.

Answers

A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.

The correct answer is:

Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.

Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.

The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.

The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.

Therefore Option B is correct.

In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?

Answers

Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.

PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.

The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.
