At which stage in meiosis I do the pairs of homologous chromosomes come together? 6. Once the chromosomes have formed a pair, what are they called?​

Answers

Answer 1

Answer:

1.) Sex organs

2.) DNA replication

3.) Sister chromatids

4.) Two identical daughter cells

5.) Late prophase 1

6.) Tetrads

Explanation:

Meiosis is a type of cell division that occurs in living organisms which involves the division of a single cell to produce four cells containing half the original amount of the parent genetic information. An example of organs that enter meiosis is the SEX CELLS.

Mitosis is another type of cell division that leads to the production of two daughter cells which are genetically identical to the parent cell. During interphase before a cell proceeds to division, DNA replication must occur. This is a process DNA uses to make a copy of itself during cell division.

Chromosomes are genetic material which occurs in pairs known as the SISTER CHROMATIDS

PROPHASE in the stage the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells

During late prophase 1 the pairs of homologous chromosomes come together to form two chromosomes and four chromatids, with one chromosome originating from each parent.

Once the chromosomes have formed a pair they are called TETRADS

Scientists find evidence of a large meteor impact on the coast of the Yucatán Peninsula in Mexico. What can the scientists most likely expect to find in the layers of rock that are about the same age as
the impact?
evidence of the mass extinction of many species
evidence of a gradual change of one species over time
evidence of a rapid change in one species
evidence of the stability of many species over time

Answers

Answer:

evidence of a gradual change of one species over time

Explanation:

Scientists can most likely expect to find evidence of the mass extinction of many species in the layers of rock that are about the same age as the impact. Therefore, option (A) is correct.

What is mass extinction?

Mass extinction refers to a widespread and rapid decrease in the biodiversity on Earth, where a large number of species become extinct within a relatively short period of time.

The impact of a large meteor on the Earth can cause widespread destruction and have far-reaching consequences, including the extinction of many species. The impact can cause a global environmental crisis, which can include the release of massive amounts of dust and debris that block sunlight, leading to a drop in temperature and changes in climate.

These changes can have catastrophic effects on living organisms, particularly those that rely on photosynthesis for survival. As a result, scientists can expect to find evidence of the mass extinction of many species in the layers of rock that are about the same age as the impact.

c. Different forces pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.
d. Same force pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.​

Answers

Answer:

a. Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.

Explanation:

The correct answer is - a.Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.

Reason -

A fault is a fracture or zone of fractures between two blocks of rock.

Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.

During an earthquake, the rock on one side of the fault suddenly slips with respect to the other.

The fault surface can be horizontal or vertical or some arbitrary angle in between.

A V-shaped valley, like the one shown, is a narrow valley with steep sides that appear to form the shape of a "V." Which statement best explains how this type of valley is typically formed? A) They are formed by weak streams, slowly wearing away rock over time. B) They are formed by forceful streams, cutting down into rock over time. Eliminate C) They are formed by massive mountain glaciers slowly moving down slopes. D) They are formed by forceful winds moving between the walls of the valley.

Answers

Answer:

The answer is B

Explanation:

In the picture there is 2 streams also I took the question myself for you and the answer was B.

This type of valley is typically firmed by forceful streams cutting down into rock over time. So the correct option is B.

What is a valley?

Valley: an extended depression on the surface of the Earth. Rivers are most often responsible for draining valleys, which can be found on relatively level plains or in between groups of hills or mountains. Rift valleys are those valleys created by tectonic activity. Gorges are the name given to similar-looking, extremely deep, narrow valleys. Despite being possible in different geological contexts, both of these latter kinds are frequently cut in strata with a flat topography.

There is potential for the land surface to develop into the well-known patterns of hills and valleys wherever there is enough rainfall. In fact, there are hyperarid regions with little activity. There are also geomorphological conditions where water cannot concentrate on the ground surface due to the permeability of the rocks or sediments causing excessive infiltration.

Therefore the correct option is B.

Organelles in the domain of Archaea do not have membranes surrounding them, in contrast to those in the domain Eukarya. So, the correct option is C.

What are Archaea?

The realm of single-celled organisms is called Archaea. These microbes are prokaryotes because they lack cell nuclei. The term "archaebacteria," which was used to describe archaea when they were first categorised as bacteria, is no longer in common usage.

Single-celled microorganisms known as archaea lack membrane-bound organelles and a cell nucleus. Archaea, like other living things, have a semi-rigid cell wall which shields them from their surroundings. Organelles in the domain of Archaea do not have membranes surrounding them, in contrast to those in the domain Eukarya.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.


competition


random chance


being the luckiest

Answers

Answer:

competition

Explanation:

An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).

A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.

Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.

B. Have long wavelengths.

C. Travel at high speeds.

D. Have short wavelengths.

Answers

Answer:

Its A

Explanation:

Its A =Have high amplitudes

Low-frequency waves have long wavelengths. Therefore, option B is correct.

What are waves?

Waves are a type of disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can take many forms, including sound waves, light waves, water waves, and electromagnetic waves.

Waves are characterized by a number of properties, including wavelength, frequency, amplitude, and velocity. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of wave cycles that occur per unit of time. Amplitude is the height of the wave, and velocity is the speed at which the wave travels through the medium.

Low-frequency waves have longer wavelengths, which means that they have fewer cycles per second (measured in hertz) and take more time to complete one full cycle. Therefore, option B is correct.

Inspiration (breathing in)

The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs. During normal breathing, the major inspiratory muscles produce rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative (relative to atmospheric pressure).
