B cells are the body’s building blocks...

The most accurate statement about cells is that they are the body's building

blocks, the units that make up all organisms.

Cells are regarded as the smallest unit of life and the different aggregations

is what forms the tissues, organs and system which make up all organisms.

This is why it is referred to as the building block of all organisms.

Organisms don't possess equal number of cells and all aren't identical as a

What is the Chemical formula for the molecule shown?

Answers

Answer:

NH3

Explanation:

Ammonia is a chemical compound formed by the chemical combination of Nitrogen and Hydrogen atoms. One Nitrogen and three hydrogen atoms are joined together by a covalent bond to form the ammonia compound. Hence, ammonia has a chemical formula of NH3.

Therefore, the molecule shown in the image, which is identified as ammonia has a chemical formula: NH3. Ammonia is a gaseous substance at room temperature and gives a pungent odor when inhaled.

what is excretion,list the ecretory product for mammals and indicate where each product is formed,make labelled of the nephron of a mammal​

Answers

Explanation:

The mammalian kidney is a compact organ with two distinct regions: cortex and medulla. The functional unit of the kidney is the nephron. Each nephron is a tubular structure consisting of four regions. It arises in the cortex as a small vesicle about one-fifth of a millimetre (0.008 inch) in diameter, known as Bowman’s capsule, into which projects a tuft of capillary blood vessels, the glomerulus. Bowman’s capsule is continuous with the proximal convoluted tubule, which also lies in the cortex. Following the proximal convoluted tubule is the loop of Henle, which descends into the medulla and then runs straight up again to the cortex where it continues as the distal convoluted tubule. A collecting tubule, into which several nephrons open, courses through the medulla to open a wide cavity, the pelvis of the kidney. From the pelvis the ureter leads to the bladder, and from the bladder the urethra leads out of the body.

Is the Earth an open, closed, or isolated system? Explain.

Answers

Answer:

Closed Systems. The earth system as a whole is a closed system. ... Virtually no mass is exchanged between the Earth system and the rest of the universe (except for an occasional meteorite). However, energy in the form of solar radiation passes from the Sun, through the atmosphere to the surface.

Explanation:

Answer:

The earth is a closed system because only energy is naturally transferred outside the atmosphere.

Explanation:

A closed system is a system in which only energy is transferred with its surroundings. An open system, however, is a system in which both energy and matter can transfer.

How do enzymes act as catalyst to speed up biological reactions

Answers

Enzymes are biological catalysts. ... Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind. This is termed "induced fit", meaning that the precise orientation of the enzyme required for catalytic activity can be induced by the binding of the substrate.on:

Answer:

Chemical reactions occur at the active site of enzymes, where a precise 3D orientation of amino acids is an important feature of catalysis.

Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate.

Activation energy is energy that must be added to get a reaction started, which is recovered as the reaction proceeds.

Enzymes can catalyze reactions through a variety of ways including destabilizing the bonds within the substrate.

Draw the phases of mitosis of a cell that contains four chromosomes as its diploid or 2n number

Answers

Answer:

Please find the diagram attached and explanation below.

Explanation:

Mitosis is a type of cell division that forms two genetically identical cells. It involves four stages viz; prophase, metaphase, anaphase, and telophase.

Considering a diploid (2n) cell with four (4) number of chromosomes.

Prophase- four duplicated chromosomes condense and pair up.

Metaphase- four chromosomes line up at the cell plate or equator in order to get separated.

Anaphase- the sister chromatids are pulled apart by the spindle microtubules

Telophase: the chromosomes recoil and organelles form at opposite poles of the cell.

At the end of cytokinesis, which is division of the cytoplasm, four chromatids are present in each daughter cell. The chromatids becomes individual chromosomes that retain the diploid (2n) chromosome number of four.

Mitosis is a cell cycle division in which the parent cell divides into two daughter cells with alike chromosome numbers.

It consists of four steps namely prophase, metaphase, anaphase and telophase.

According to the question, the diploid (2n) cell with four chromosomes will divide by the following stages. Find the attached image below for the diagram:

Prophase- four copied chromosomes will consolidate and pairing will happen.

Metaphase- the joined chromosomes will queue at the middle of the cell plate or equator.

Anaphase- the sister chromatids begins stretching apart by the spindle micro tubules near the edge of the poles.

Telophase: the chromosomes commence recoiling and other organelles start developing at the corresponding poles of the cell.

This was the process of karyokinesis and will be followed by cytokinesis that is the cytoplasm division.

Now the chromatids will become individual chromosomes and two diploids (2n) daughter cells will be formed.

Explanation:

To set up a control group, you pick individuals at random( so you don't just get a group to be of the same character, or opinion).

The control group is vital in every experiment because, sometimes our hypothesis could be mere coincidence or assumptions. So the control group will be compared to the test group to see if the results are correct. Plus look at it this way, without a control group, your hypothesis wouldn't be a theory.

A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability.

Moreover, a Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things. Circles that overlap have a commonality while circles that do not overlap do not share those traits.

A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items. Often, they serve to graphically organize things, highlighting how the items are similar and different.
