The unicellular green alga Chlorella is often used as a model organism to study the effects of various substances on the growth of photosynthetic organisms. Researchers studying the detoxification of certain metals by Chlorella first collected data on the growth dynamics of the alga. A small number of Chlorella were added to 1,500 mL of culture medium that contained all of the inorganic nutrients needed for growth. Every five days for 30 days, the researchers performed multiple counts to determine the concentration of Chlorella in the culture. a. Describe why the amount of light available to the Chlorella culture might affect the growth dynamics of the alga.

Answers

Answer 1

Answer:

It depends on the light for its growth.

Explanation:

The amount of light available to the Chlorella culture might affect the growth dynamics of the algae because Chlorella is just like plant that prepare their own food with the presence of light. If there is more amount of light received by the Chlorella algae, it prepare more food and more growth occurs while on the other hand, if there is less amount of light available to Chlorella algae so it produce less amount of food and less growth will occur.

They cause less pollution

Pls help ty

Answers

They cause less pollution. Renewable sources of energy, such as solar, wind, and hydroelectric, cause significantly less air and water pollution than non-renewable sources, such as coal and oil.

What is pollution?

Pollution is the presence of toxic substances in the environment that can have a negative effect on humans, animals, and plants. It can either be the result of natural processes or due to man-made activities. Pollution can occur in the air, water, soil, and even in the food we consume. Common forms of pollution include air pollution, water pollution, plastic pollution, and noise pollution. Air pollution is the release of pollutants into the air which can cause harm to humans and the environment. Water pollution is the contamination of surface or ground water and can be caused by agricultural runoff, industrial pollution, and sewage. Plastic pollution is the accumulation of plastic particles in the environment that can damage ecosystems.

All of an organism's characteristics are inheritable which evolves over millions of years. An example of this is the modern day horse's foot.

What is Evolution?

This is referred to as the change in the heritable characteristics of biological populations over successive generations.

All an organism's characteristics can be inherited and evolves over a period of time as a result of the changing environmental conditions which helps them to adjust thereby increasing their chances of survival hence preventing extinction of species.

For example, over millions of years of evolution, many horses lost their side toes and developed a single hoof as a result of them needing to move at faster speeds to evade predators.

the energy role responsible for capturing the energy from the sun and turning it into food is a

A. producer

B. Consumer

C. Decomposer

Answers

Answer:

A. Producer

Explanation:

The primary source of energy for almost every ecosystem on Earth is the sun. Primary producers use energy from the sun to produce their own food

Answer:

Hi, there the answer is A. producer

Explanation:

All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.

A small proportion of humans have resistance to strains of HIV, the virus that causes AIDS. Their immunity is caused by a deletion in gene CCR5, a co-receptor on white blood cells needed for HIV infection. The proportion of people with resistance (genotype aa) to HIV is approximately 8%. If these alleles are in Hardy Weinberg equilibrium, what proportion of people are carriers for the HIV resistant allele?

Answers

Answer:

The correct answer is "40.6%". A further explanation is provided below.

Explanation:

The given values are:

The proportion of people with resistance is,

aa = 8%

or,

    = 0.08 (q²)

= 0.08

q   = √0.08

    = 0.28284

Now,

⇒ [tex]p+q=1[/tex]

⇒       [tex]p=1-q[/tex]

             [tex]=1-0.28284[/tex]

             [tex]=0.717157[/tex]

hence,

For the HIV resistant allele, the proportion of people will be:

= [tex]Aa[/tex]

= [tex]2pq[/tex]

On substituting the values, we get

= [tex]2\times 0.71715\times 0.28284[/tex]

= [tex]0.4056[/tex]

= [tex]40.6[/tex] (%)

The proportion of the population with the carrier of HIV-resistant allele is 40.56%.

What is Hardy Weinberg equilibrium?

Hardy Weinberg equilibrium is the relationship between the variation from one generation to the next. The equation for the relationship can be given as:

[tex]p^2+2pq+q^2=1[/tex]

Where the proportion of dominant alleles is p².

The proportion of recessive alleles is .

The proportion with the caries are 2pq.

The given recessive allele proportion in the population is 0.08. The proportion of dominant alleles can be given as:

[tex]q^2=0.08\\q=0.2828[/tex]

The dominant alleles can be given as:

[tex]p+q=1\\p+0.28284=1\\p=0.717157[/tex]

The carriers in the population can be given as:

[tex]\text{Carriers}=2pq\\\text{Carriers}=2\;\times\;0.717157\;\times\;0.2828\\\text{Carriers}=0.4056\\\text{Carriers}=40.56\%[/tex]

Thus, the carriers for the HIV gene in the population are 40.56%.

When blood passes through a capillary bed in the
it downloards O2 and uploads CO2.

Answers

Answer:

Exchange of gases takes place at alveoli sacs of lungs, which are equipped with capillary vessels or bed.

Explanation:

On inspiration or taking air through nostrils, surrounding air enters the lungs and it reaches air sacs or alveoli. Here, the outside air will have more amount of oxygen when compared with oxygen in blood at that site. Hemoglobin in the blood have high bonding capability to oxygen, so it captures oxygen and takes it to heart for pumping into other parts of the body. Likewise, the circulations continues from lungs to heart > hear to body parts > body parts to heart > heart to lungs for purification.

What are air masses, and how do they work? Don't copy and paste.

Answers

What are Air Masses:  They large volumes of air that have generally the same temperature and pressure.

How they work: One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down.

Example of an Air Mass: The air masses in and around North America include the continental arctic, maritime polar, maritime tropical, continental tropical, and continental polar air masses. Air is not the same everywhere.

Fact: Unstable air masses have different temperatures and pressures.

How they are formed: An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.

*** The Earth's major air masses originate in polar or subtropical latitudes.

Does every gene combination show up in the offspring?

Answers

Answer:

Answer!

Explanation:

Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.

Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.

Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.
