Which growth model is a realistic representation of population growth?

A realistic representation of population growth is the _____ growth model.

Answers

Answer:

Logistic Growth Model

Explanation:

The logistic model is realistic because it suggests the fact that the population of species is regulated and controlled by the carrying capacity (maximum members that an ecosystem supports) of the ecosystem. The population becomes small when the carrying capacity decreases.

Why are groups of small cells better than one large cell at moving material in
and out?
A. They have a smaller volume.
B. They have more cell structures,
C. They have a greater surface-to-volume ratio.
O
D. They have a lower surface-to-volume ratio.

Answers

Answer:

C. They have a greater surface-to-volume ratio.

Explanation:

Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.

For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.

Even though the tubers are genetically identical why the plants that grow from them may not be the same height ?
please explain


Please answer correctly.​

Answers

Answer:

I've grown potatoes on top of loose earth that's covered by a thick layer of loose straw. It allows the green leafy parts to easily push through to the sunlight above while keeping developing tubers protected from light. I've grown them this way because I really enjoy the taste of fresh new potatoes and have no desire to store mature potatoes for winter. I want to get the most baby potatoes possible while not damaging the plants with tiny potatoes not big enough to eat yet. It also keeps the potatoes cleaner than if grown under the soil.

When I start lifting the straw back to pick the largest new potatoes, I can see the development of the other potatoes. While the biggest potatoes are 1 1/2 to 2 inches in size, others range in size all the way down to 1/4 inch or less.

When a specific garden plant blooms, most of the flowers open within a very short time period. Now think of tomato plants. The flowers continue to open over a period of months and both ripe tomatoes, large and small green tomatoes as well as flowers can all be found on the same plant. Not all the fruit will be ripe before cold weather kills the plant.

Potatoes are closely related to tomatoes and like tomatoes, not all the tubers will be full size when the plant dies back. So I'd say it's neither genetics nor environmental factors but the inherent life and growth cycle of potatoes that account for the tuber size difference.

The difference in the tuber size in plants of potatoes and tomatoes does not depend upon its genetics or environmental factors rather it depends upon the inherent life and growth cycle of the plant.

What is the growth cycle in potatoes?

Growth cycles are the recurrent fluctuations in the series of deviations from the usual trend of the plant growth. Thus, the growth cycle contractions in the plant include slowdowns as well as absolute declines in the activity, whereas business cycles contractions include only the absolute declines or recessions.

Potatoes are the plant species which are closely related to tomatoes and just like tomatoes, not all the tubers will be full size when the plant dies back in time. So, it is neither the genetics nor the environmental factors but the inherent life and growth cycle of the potato plants that account for the tuber size difference in the plants which are genetically identical to each other.

What is an Obligate anaerobe? How do obligate anaerobes, like the bacteria C. Botulinum, get energy ?

Answers

Answer:

See the answer below

Explanation:

Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level.

Obligate bacteria such as Clostridium botulinum obtain their energy through anaerobic respiration processes such as fermentation and anaerobic respiration. During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.

You are viewing an organ of the respiratory system and note the following tissues: folded mucosal layer containing simple cuboidal epithelium and smooth muscle, shifting into simple squamous epithelia. Identify the organ.

Answers

Answer:

Respiratory bronchiole  

Explanation:

The respiratory bronchioles represent the narrowest airways within the lung, being continuations of terminal bronchioles that have approx. 0.5 mm in size. The epithelium of the respiratory bronchiole is composed of cuboidal ciliated cells and a small number of non-ciliated (secretory) Clara cells. The respiratory bronchioles lead into alveolar ducts composed of smooth muscle and connective tissue (i.e., elastin and collagen), connecting the respiratory bronchioles to the alveolar sacs.

Determine which of the following statements is true about energy in ecosystems A. Consumers pass on 20% of the energy they get from a lower trophic level. OB. Primary consumers lose 60% of the energy they absorb from producers as urine and feces. C. 10% of the energy Primary consumers absorb is lost as heat. Ons Primary producers lose 20% of the energy they absorb as urine and feces.​

Answers

Answer: C. 10% of the energy Primary consumers absorb is lost as heat.

Explanation:

According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.
