all of the types of cells pass through the cell cycle at the same rate? *
1 point
Yes. All of the cells divide at approximately the same times throughout the life of the
organism.
Yes. All of the cells divide at approximately the same rate, although they may divide at
different times.
No. Some specialized cells, such as skin cells, divide much more rapidly than other
specialized cells
No. Some specialized cells, such as skin cells, divide much more slowly than other
specialized cells.

Answer:

the number of chromosomes each time gets halved

so the first division will have 13 in each daughter cell

and the second will have about 3 in each daughter cell

Answer:

All of the choices are ecosystem services.

Explanation:

Trees' roots hold soil down so it doesn't move everywhere and they recycle carbon into oxygen. In addition, they provide us wood and beautiful wildlife!

Have a great day!

The ecosystem services are all the benefits provided by the ecosystem to human. Otion A) habitat for wildlife is not an ecosystem service.

When talking about ecosystem services, we are referring to the goods and services offered by ecosystems to human populations

There are different types of ecosystemic services:

These are the products obtained by nature to be used or consumed, directly or with previous processing.

Among them, we can mention food, clear fresh-water, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, and others.

Refers to ecological processes that improve life.

Among others, we might mention climate regulation, CO₂ absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil formation and fertility maintenance, nutrient cycling, waste recycling, pests/plagues control, etc.

Refers to the benefits that are not material.

Ecosystems also provide a recreational place or area to spend time, learn. They are a spiritual/religious space, a source of inspiration. They are considered to be cultural patrimony and the source of scientific knowledge.

Among th options, the one that is not a ecosystemic service is option A) habitat for

Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.

Answer:

It is D

Explanation:

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Answer:

1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.

3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II 

● PhotosystemSII acts first during the light transformation process in photosynthesis.

● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from 

plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.

Answer:  

Severe flooding is caused by atmospheric conditions that lead to heavy rain or the rapid melting of snow and ice.

Explanation:

Because the total of neutron and proton/electron is the atomic mass. So if you wanna find proton/electron and you know the neutron, just minus the atomic number with the neutrom and you will get the proton

Here if you need the formula

Atomic number = Total neutron + Total proton or electron

Answer: c) geology, archaeology, and paleontology

Explanation:

The geological time scale can be defined as a scale which is used to determine the chronological dating of the organisms in the geological strata. It helps in determining the occurrence and existence of particular kind of species on planet earth. It can also be used to trace the development and passage of a particular kind of trait from one generation to the another. It can also be used to trace back various geological events that occurred on planet earth like volcanic eruption, plate tectonics, and others. The geologists used it for tracing the geological activities that occurred in the history of earth. Archaeologist study about rocks and fossils to trace back the geological time scale. Paleontologist study the existence of a particular species via studying the fossil evidences and reconstructing the primitive conditions by developing a geological time scale. They trace the evolutionary history of organisms.

Answer:

1. 0.79g/mL

2. Ethanol

Explanation:

The density of a substance can be calculated by using the formula;

Density (g/mL) = mass (g) ÷ volume (mL)

According to the information provided in the question, mass = 11.85grams, volume = 15mL.

Hence, density = 11.85g ÷ 15mL

= 0.79

Density of the liquid = 0.79g/mL.

Substances usually have their own unique density, which is one of the properties that distinguish them. In this case, ETHANOL is the liquid that possesses a density of 0.79g/mL.

Answer: Scientists say that energy can neither be created nor destroyed, so therefore it is impossible for there to be an energy crisis.

Explanation:

I'm pretty sure I'm right

Answer:

There is a problem because if energy is created as machines worked everything would speed up until it breaks, and if energy was destroyed as machines worked everything would eventually slow down and stop. So in both cases the world would end, a whimper in one a bang in the other.

Answer:

an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment

Explanation:

An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.

Answer:

A, B, C, and D

Explanation:

All of the options represent ways by which humans can lower biodiversity as they use the environment.

By definition, biodiversity or biological diversity of an area refers to the total number of living organisms that are domicile in that area.

Converting a forest to a soccer field requires that the variety of plants and animals in the forest are removed and the forest soil is planted with turfs in their place. Thus the biodiversity of the forest has been greatly reduced in other to pave way for a soccer field.

A pesticide is an agrochemical that kills pests. Pests are biological organisms even if they are not that desirable on the lawn. Thus, killing them off using a pesticide is a way of reducing the biodiversity associated with the lawn.

A tundra represents an ecoregion with its own characteristic plants and animal, even if they are few. Hence, building roads across tundra requires that portions of the biodiversity are removed to pave way for the road.

Riverbanks serve as habitats for a variety of living organisms. Replacing them with concrete bulkheads means that the habitat is lost and the organisms displaced. Thus, the biodiversity of the region gets reduced.

Therefore, options A, B, C, and D are all correct.

Answer:

The correct answer is - option C. Electrical Energy, heat energy, light energy.

Explanation:

The transformation of energy from the light switch to the light bulb starts with the electrical energy to the heat or thermal energy and also generates the light energy which lights the bulb.

The amount of electrical energy is equal to the amount of light energy plus the heat energy generated by the bulb. It did not get mechanical or chemical energy.
