What did you include in your response? Medications can be tested on cell cultures instead of being injected into patients unnecessarily. Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells. Specific treatments that are shown to fight the growth of cancer cells in the culture can be used on patients. Cultures are safer to use than injections of unneeded medications into patients.

Answers

Answer 1

Answer:

The statements are correct.

Explanation:  

Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.  

Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.

Mutation may occur in gametes or in body cells. In which cell type is a mutation likely to be source of genetic variation for ?

Answers

Answer:

Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1​ que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2​

En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3​ Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.

In photosynthesis, plants use _______ and release ________. *

A. carbon dioxide, oxygen
B. oxygen, carbon dioxide

Answers

Answer:

A. carbon dioxide, oxygen

Explanation:

Photosynthesis is a process that certain organisms (plants, algae and some bacteria) undergo to produce their own food. The equation for photosynthesis is:

water + carbon dioxide + light energy —> glucose + oxygen

In photosynthesis, the plant takes water, carbon dioxide and light energy from the sun and turns it into glucose (sugar, or the food) and oxygen.

Therefore, the correct answer is A. carbon dioxide, oxygen. The plant will use carbon dioxide and then release oxygen as a waste product.

Genetic drift and natural selection can both be mechanisms of evolution. However, they are very different mechanisms. Explain how genetic drift is different from natural selectio

Answers

Answer:

Explanation:

Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.

Why does mining have such an impact on the environment? A. Mining only affects the living parts of the environment. B. Because minerals are within the Earth's surface, extraction causes destruction. C. Mining requires the absolute destruction of an area to be cost-effective. D. Areas that are mined can never again sustain plant life. Please select the best answer from the choices provided A B C D

Answers

Answer:

B.

Explanation:

The primary environmental effects of mining are on the habitats for wildlife and fisheries, the water cycle, regional temperatures and rainfall patterns, sedimentation, forest loss, and ecological disruption. Thus, option B is correct.

What is the impact of mining on the environment?

The effects of mining on the environment include soil, groundwater, and surface water contamination from chemicals produced during mining operations, erosion, sinkhole development, biodiversity loss, and sinkholes.

Mineral extraction from the environment frequently results in imbalances that are harmful to the environment.

Loss of vegetation cover, widespread water body degradation, biodiversity loss, altered land use, increasing social vices and conflicts, high cost of living, and air pollution are some of the negative effects of mining.

Therefore, Because minerals are within the Earth's surface, extraction causes destruction.

1.Nitrification happens when soil organisms change over ammonium into nitrate.

3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

2. Assume that crossing over does not occur in the region of each chromosome that is associated with the centromere. You have 46 centromeric regions in each cell, 23 that are copies of the DNA in your mother’s egg and 23 that are copies of the DNA father’s sperm. Show your work for A,B,C a. For any given gamete, what is the probability that all the centromeric regions (chromosomes) will be copies of the same ones that you received from your mother? b. It has been estimated that the average person is heterozygous for at least 2,000 protein forming genes. How many different kinds of gametes is it theoretically possible for each person to produce? c. Considering the maternal and paternal origin of the centromeric regions alone, how many different kinds of gametes can you produce?

Answers

Answer:

See below

Explanation:

A. centromeric regions from mother in one cell: 23

total number of centromeric regions in one cell: 46

for every centromeric region that is inherited by the gamete, there is a 0.5 probability that it is from the mother. Hence, if all are from the mother:

0.5 ^ 23 = 1.19 x 10^(-7)

B. Heterozygous for 2000 genes means 4000 possible alleles.

2 ^ 4000 = 1.3 x 10^(1204)

C. 2 ^ 46 = 7.03 x 10^(13)

When multiple glaciers start their downward flow from a single point, they create a .

Answers

Answer:

They create a Mountain Peak

When multiple glaciers start their downward flow from a single point, they create a Mountain peak. So, the correct option is B.

What are Glaciers?

A glacier is a sizable, slowly moving mass of ice that develops over a considerable amount of time as a result of the buildup of snow and ice. In areas where the average temperature is below freezing and there is enough snowfall to offset the melting that takes place during the summer, glaciers can be discovered. They can occur at lower elevations in some places, although they are mainly found at high altitudes or in the polar regions.

When several glaciers begin to flow downward, they build something resembling a pyramid. The mountain peak is created as a result of the glacier's movement from a single location. Due to the simultaneous movement of several glaciers to the ground, a pointed structure has recently created.

Therefore, the correct option is B.
