Answer:

Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis.

Explanation:

Pollen grains contain the male gametes of a sexually reproducing plant. Pollen grains are haploid cells in nature produced by the meiotic division of microspore mother cells (located in the anther). The meiosis of these diploid (2n) microspore mother cells give rise to four haploid microspores. This process in plants is called microsporogenesis.

Each haploid microspore (n) develops into pollen grain called microgametophye (bearing male gamete) via mitotic division. During the pollen grain formation, a wall is formed around the microspores.

Which most accurately describes the basis of the scientific method? A.) a path of clearly defined steps that must be followed in a particular order B.) a possible answer to a scientific question based on knowledge or research C.) the recipe for how to conduct an experiment that must be followed precisely D.) the process of hypothesis and testing through which scientific inquiry occurs

Answers

The statement 'the process of hypothesis and testing through which scientific inquiry occurs' most accurately describes the basis of the scientific method.

The scientific method is a series of sequential steps used to build scientific knowledge.

The steps of the scientific method include:

To make observations about a given phenomenon of the natural world and formulate questions based on these observations.

To pose a plausible explanation (i.e., a hypothesis) in order to answer these questions.

To test the working hypothesis by experimental and/or observational procedures.

To collect data in order to confirm or reject the working hypothesis.

Examine results and draw conclusions.

In conclusion, the statement 'the process of hypothesis and testing through which scientific inquiry occurs' most accurately describes the basis of the scientific method.

What helps water move across the
membrane quicker?

Answers

Answer:

The sell membrane

Explanation:

Hope it helped

Answer:

A channel protein

Explanation:

A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly. Water channel proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate. Ion channel proteins allow ions to diffuse across the membrane.

Given what you know about cellular organelles, what problems do you predict a cell would have if it had a defect in a lysosomal enzyme

Answers

Answer:

Cells without lysosomal enzymes will not be able to digest food and these will lead to accumulation of wastes in the cells, leading to cancerous growth and the cells will not be able to live long.

Explanation:

Lysosomes is a membrane bound organelles found in eukaryotic cells that produce lysosomal enzymes which help to breakdown or engulfs biomolecules like proteins, carbohydrates, nucleic acids, lipids it engulfs in the cells to molecules it will easily be absorbed.

Without these enzymes or defect in these enzymes, biomolecules will not be broken down and it's resultant effect is accumulation of wastes which can lead to cells destruction.

Which of the following types of cells suppress immune responses?a. Neutrophilsb. Plasma Cellsc. Macrophagesd. Regulatory T Cells

Answers

Answer:

The correct answer is d.

Explanation:

Regulatory T-cells are a class of T cells which are part of the immune system that suppresses immune response. They are called regulatory because they assist in "checking" the excesses/overreaction during immune response.

NOTE:

Neutrophils are phagocytic in nature; they ingest and destroy microorganisms or other foreign molecules.

Plasma cells synthesize antibodies which are produced in response to antigens. They are target foreign particles for digestion by other immune cells.

Macrophages are also phagocytic in nature usually found at sites of an infection.

4. Distinguish between the types of scientific

investigations. Does all scientific knowledge

come from experimentation? Explain your

answer. SC.7.N.1.3

Answers

Answer: Descriptive, Comparative and Experimental (which comes from experimentation).

Explanation:

There are three types of scientific investigations:

Descriptive: This type of scientific investigation studies parts of a system, which can be natural or artificial. It describes everything that is being studied and no predictions are made. There are three types of descriptive methods: case-study methods (an in-depth study is produced from many sources with different methods), observational methods (no questions asked, just an observation of the behavior of a subject and no manipulation of the variables), and survey method (some people are interviewed and the researchers study the answers.)

Comparative: It gathers information from organisms, systems, places or from any source, to compare them using also a control group. But, there is no imposed treatment because it is not ethical or because it is not possible. So, the treatment is only observed.

Experiment: As its names says, it uses an experimental test designed to study some phenomena, where variables are controlled so the treatment is not only observed as the comparative method. Then those variables are measured to collect information or evidence that supports or not a previous hypothesis and is used to assess theoretical knowledge. The independent variable is manipulated while the dependent variable is measured. This type of scientific investigation comes from experimentation.

A student wants to illustrate the number of each different bird species that migrates south in winter. Which type of chart/graph would be the most appropriate to use?

a
Pie Chart
b
Bar Graph
c
Line Graph

Answers

Answer:

bar graph

Explanation:

A bar graph

You want to show that there is no connection between one species and another.

The line graph will do exactly the opposite. It will imply that the line joining 2 points gives some connection between one point and the next point.

The Pie chart is usually used to compare one number size with a another, like the total number of Covus 19 by state each state close to the other. It is not a good choice because California (for example) might have the most number of cases of the virus but it also has the largest population. You might use the pie chart by converting it to %s, but what would that give you, and how could you use it.

Which statement best compares and contrasts lipids and carbohydrates?

HURRY PLEASEE I HAVE TWO MINUTES JUST THE LETTER AWNSER

Answers

The correct answer is B. Both are used for energy storage, but only carbohydrates are used for short-term energy.

Explanation:

Carbohydrates and lipids are both biological macromolecules, which means they are essential for living organisms. Additionally, these are similar because they store energy. However, the type of energy they store is different.

Indeed, carbohydrates store short-term energy, which means carbohydrates are broken down a short time after ingested, and the energy in them is used. On the other hand, in lipids, the energy store is long-term energy, which means it is not consumed as fast as in carbohydrates. This occurs because lipids contain more energy. According to this, the correct statement is "Both are used for energy storage, but only carbohydrates are used for short-term energy".  

Answer:

B

Explanation:

Both are used for energy storage, but only carbohydrates are used for short-term energy storage.
