1. Question: How does temperature affect the growth of bacteria?
Procedures: A scientist places three different petri dishes in 20C, 35C,
and 60C. After 2 days, the number of bacteria colonies were counted.

Answers

Answer 1

Answer:

It directly affects

Explanation:

Bacteria are conditioned by external environmental factors such as partial pressure of oxygen, humidity, temperature, metabolites, radiation present, living with other types of colonies, partial pressures of carbon dioxide, etc.

The growth of a colony will always be better or worse as long as the ideal environmental conditions are met for that bacterium to nurture and develop widely.

In general, the ideal temperature is around 37 degrees for most bacteria, although it also depends a lot on the presence of the substrate they need to live and give their necessary metabolites.

The role of the ___________ branch of the autonomic nervous system mediates control of organ processes when the body is essentially ______.

Answers

Answer: parasympathetic; at rest

Explanation: The parasympathetic nervous system branch of the autonomic nervous system is largely responsible for the relaxation of the body especially at rest where it undoes the activities of the sympathetic branch by decreasing respiration, heart rate and then increasing the body's digestion rate. As such, this branch is also responsible for digestion response in a relaxed, resting, or feeding states. The role therefore of the parasympathetic branch of the autonomic nervous system mediates control of organ processes when the body is essentially at rest.

Biologists designed an experiment to test the effects of compost on the development of root crops

Answers

Answer:

The crop has good yield because Compost has a good effect on root crops.

Explanation:

Compost has a great effect on the development of root crops such as onion, potato, garlic and ginger etc. Compost provide nutrients to these crops as well as soften the soil due to which they grow rapidly. It also improved ventilation, soil structure and soil texture which is very necessary for the crop. Due to ventilation, oxygen gas is available to the roots which increases growth and yield of these crops. Compost also retain water and nutrients so they are available to the roots. So those plots where compost is applied observed increase in yield as compared to other plots.

Describe the transport properties of the loop of Henle and explain the interactions between the ascending and descending limbs

Answers

Answer:

The loop of henle is a part of the renal functional unit.

This handle has an ascending part and a descending part.

In the descending loop, the urine that is formed inside enters a hypotonia, since a large amount of water is absorbed and the concentrations of solutes in the urine decrease, thus generating a hypoosmolar solution, that is, with less molarity.

In the ascending loop of henle, the opposite arises, ionic channels appear that increase the concentration of solutes, this is how the urine that runs through the interior of the ascending loop of henle becomes hyperosmolar.

Hyperosmolarity is the increase in concentrations of solutes, and the increase in molarity of the solution, which in this case would be urine.

Explanation:

A very important fact is that urea is absorbed in the ascending henle loop.

What is a biological approach to determining when a mother and her conceptus become separate individuals?

Answers

Answer:

Electroencephalography.

Explanation:

Electroencephalography is used to measure brain activity in terms of electrical activity. It is done by attaching electrodes on the scalp, or sometimes by placing electrodes directly in the brain. Using electroencephalography can help determine when the fetus starts having its own brain activities, which means that it is now a separate entity distinguishable from its mother. Using electroencephalography to see brain waves can give us a deeper insight into the age old complicated issue of when a mother and her conceptus become separate individuals.

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probability the offspring inherita
recessive short allele. (I point)
75%
25%
0%
50%

Answers

Answer:

The correct answer is - 25%

Explanation:

A cross between true tall pea plant and heterozygous tall pea plant is the cross of tall allele whic is TT and heterozygous which is Tt, so the gametes will be formed would be - T and T by true tall plant and T, and t allele by heterozygous plant.

The Punnett square of this cross is attached with the answer, where 2 heterozygous offspring and two tall offspring produced. In which there is only two recessive short allele formed in this generation out of 8 alleles.

So the probability of short allele would be:

= (2/8) *100

= (1/4) *100

= 25%

A red flower producing snapdragon plant is crossed with a white flower producing snapgragon plant. Resulting F1 generation is crossed with one another to produce F2 generation.

This is incomplete dominance of genes.

Q1 What type of a breeding is this? (monohybrid, dihybrid or interspecific)

Q2 Draw a genetic chart to show P, F1 and F2 generations clearly indicating genotypes, phenotypes and generations.



Answers

Answer:

See the answer below

Explanation:

1. This is an example of monohybrid breeding. A monohybrid breeding is the type of breeding that involves parents with a pair of contrasting characters. On the other hand, a type of breeding involving a single gene is what is known as monohybrid breeding.

2. When a red flower snapdragon is crossed with a white flower snapdragon, the resulting offspring are usually pink - an indication of incomplete dominance of the gene responsible for flower color. Assuming the red flower's genotype is AA and that of the white flower is aa:

                       AA      x      aa

                 Aa      Aa      Aa      Aa

F1 genotype = all Aa

F1 phenotype = pink flower

At F2:

                          Aa      x      Aa

                 AA         2Aa           aa

F2 Genotype/phenotype:

       1AA - red color

       2Aa - pink flower color

        1 aa - white flower color.

Food microbiologists are scientists who have a background in both microbiology and food science. They focus on how microbes grow, cause disease, and how they can be identified from food. Their work is of importance to the food industry as it relates to the production, preservation, and spoilage of food; and it is of importance to public health and regulatory agencies due to the many diseases that are related to food intake and consumption. Food microbiologists can have varying backgrounds, including training in veterinary medicine. This scenario is about a food microbiologist who works as a food safety inspector who pays a visit to a cheese manufacturing plant and makes some interesting discoveries!
Part A-Understanding the Role of Microbes in Fermentation The Midwest is known for its contribution to the dairy industry Fermented dairy products include milk, yogurt, and cheese. The fermentation process relies on lactic acid bacteria and pasteurization. Fermentation can vary based on what food is being produced, the type of bacteria used to produce lactic acid, and the time and temperature of pasteurization. It is important to the manufacturer to produce a product that won't spoil before it is packaged and sold and that won't result in disease for those who ingest and enjoy it. Julie, a food inspector for a local Michigan health department is going to a nearby cheese plant for a biannual inspection. When she gets there, she will take a tour of the plant and allow the operators to describe what makes their cheese so special. She will use what she understands about fermentation to inquire about their production practices Please sort the following statements as being true or false regarding fermentation and its role in food production. Please recall the role that microorganisms can play in the production of foods.
1. Fermentation allows for sugars to be broken down

You perform a test cross of the dihybrid AaBb and score the phenotypes of 1000 progeny. Assuming independent assortment, how many of the progeny do you expect to display the dominant phenotype for both the A and B genes?

Answers

Answer:

4

Explanation:

The number of progeny expected to display the dominant phenotype for both the A and B genes should be  4.

A test cross usually involves crossing an individual whose zygosity is in doubt with an individual that is recessive for both alleles so as to ascertain the zygosity of the former. Hence, for a test cross involving AaBb:

             AaBb     x     aabb

Progeny:

4 AaBb

4 Aabb

4 aaBb

4 aabb

Therefore, the number of progeny expected to display the dominant phenotype for both the A and B genes is 4.

"I can be single celled or multicelled. I can reproduce sexually or asexually. I can be heterotrophic or autotrophic. I am Eukaryotic. What am I?"

Answers

Answer:

The correct answer is a protist.

Explanation:

A eukaryotic organism, which cannot be categorized as an animal, plant, or fungus is known as protists. They are majorly unicellular, however, some of them are multicellular like algae. Some of the protists can attain energy for living by consuming other organisms, that is, they are heterotrophic. While some obtain energy from the surroundings via the process of photosynthesis, that is, they are also autotrophic.  

The protists are mainly found in water, however, some of them also thrive in moist soil. These species can be seen anywhere on the Earth, where there is liquid, even within human beings. The reproduction is some of the protists takes place sexually, that is, with the help of gametes, while in some of the protists asexual reproduction also takes place, that is, by the process of binary fission.

D. synthesized by organisms at level D.

Answers

Answer:

B. passed through levels A, B, and C to organisms

Explanation:

DDT is an insecticide that passed through the food chain from one trophic level to the next.

The concentration of DDT increases with the each trophic level in food chain and the amount of toxin increases as passes from A to B, B to C, and C to D where D has the higher concentration of DDT as it is the higher trophic level than A, B, and C.

Hence, the correct answer is "B. passed through levels A, B, and C to organisms".

a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt.

Nutrient:
1. Iron
2. Vitamin A
3. Vitamin D
4. Iodine

Answers

Answer:

a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables. - Vitamin A

Sabita is suffering from Vitamin A deficiency. A lack of Vitamin A usually shows itself with night blindness but can cause complete blindness if not acted upon quickly.

Vitamin A deficiency is quite common in developing or poorer nations such as the area Sabita is located and usually attacks children of women in their reproductive stage. Sources of vitamin A include; fortified milk, animal products and fruits and vegetables.

b.  Sabita has an enlarged thyroid gland due to a dependence on unfortified salt. - Iodine

Iodine deficiency leads to an abnormal enlargement of the thyroid gland leading to a condition known as Goiter which presents itself as a big bulge in a person's neck. Iodine is usually placed in fortified salt along with iron to reduce iodine deficiency so Sabita's dependence on unfortified salt is robbing her of a great source of Iodine.

The condition in which the body is deprived of minerals, vitamins and other macro and micronutrients are called malnutrition.

The correct matches and their explanation are as follows:

a. The correct answer is:

Option 2. Vitamin A

Sabita is blind from meals deficient in fortified milk, animal products, fruits and vegetables due to Vitamin A deficiency.

Night blindness is a common symptom of a Vitamin A deficiency.

It is most common in developing regions due to the lack of proper meals. The best source of vitamin A is milk, fruits and animal products like eggs.

b. The correct answer is:

Option 4. Iodine

Sabita has a swollen thyroid gland due to habituation on unfortified salt deficient in Iodine.

Iodine deficient diet causes thyroid gland enlargement a disease called Goiter. This type of disease also affects glucose metabolism and weight.
