Which one is the correct answer?

The intermediate states between an ancestral form and that of its

descendants are transitional fossils.

Transitional fossils are remains of an organism that came in between a known version of a species and the current species.

Transitional fossils would be proof of evolution because they would show medium forms of a species and they altered and accumulated adaptations at a slow pace.

Thus, option "D" transitional fossils are correct.

Answer:

(b) Digestive tract and liver

Explanation:

The digestive system consists of the digestive tract and liver. The digestive tract is made up of a large number of parts. These parts include the esophagus, stomach, intestines, rectum, etc. Food enters the mouth and travels down the digestive tract and out passing the rectum. The liver is where the blood passes through and it is responsible for many functions such as the metabolizing of fats and proteins, separating and storing vitamins and minerals, regulating different chemicals found in the blood, etc.

Answer:

 The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom.

Answer:

1/4 WR; 1/4 wr; 1/4 wR; 1/4 Wr

Explanation:

The principle of independent assortment indicates how different genes independently separate from one another when gametic (reproductive) cells develop. When a cell divides by meiosis, homologous chromosomes are randomly distributed to daughter cells, thereby different chromosomes segregate independently of each other. In consequence, each gamete has a unique combination of chromosomes. In this case, the two genes are on different homologous chromosomes, thereby gene variants (alleles) will be randomly distributed to daughter cells during meiosis (anaphase I) and thus the expected proportion of gamete genotypes will be 1/4 WR, 1/4 wr, 1/4 wR, 1/4 Wr.

Answer:

The correct answer is - due to the different bacteria that produce a different enzyme that is involved in the fermentation of malic acid.

Explanation:

In red wine production, malic acid in present in grapes converted to a softer lactic acid. This process is known as malolactic fermentation. It takes place due to the presence of different types of bacterias such as bacteria of the lactic acid family.

These bacterias produce enzymes which is used to convert the malic acid to lactic acid such a process can occur naturally also.

Answer:

- Contains myelinated axons: White matter

- Posterior column: White matter

- Located to the periphery of the spinal cord: White matter

- Gracile fasciculus: White matter

- Anterior spinocerebellar tract: White matter

- Medial vestibulospinal tract: White matter

- Marked by low myelination: Gray matter

- Functions to integrate arriving electrical signals: Gray matter

- Contains somas, synapses, and dendrites: Gray matter

- Tectospinal tract: White matter

- Functions to transmit electrical signals rapidly over long distances: White matter

- Lateral horn: Gray matter

- Ventral horn: Gray matter

Explanation:

Both the brain and the spinal cord contain white matter and gray matter. White matter is the tissue responsible for information transmission (i.e., axons); whereas gray matter is mostly involved in information processing (i.e., neuron bodies). White matter is composed of myelinated axons which extend out from the neuron bodies and glial cells, and this tissue connects different areas of the cerebral cortex (i.e., the outer layer of the brain). Moreover, gray matter is composed of neuronal cell bodies or 'soma'  that contain the neuron’s nucleus and unmyelinated axons. Gray matter also has glial cells and capillary blood vessels; whereas white matter also has oligodendrocytes that produce myelin and astrocytes. The color of the white matter is caused by the myelin that surrounds the axons; while the color of the gray matter is due to the capillary blood vessels and neuronal cell bodies. In the cerebrum and cerebellum, white matter is observed in deep areas coated by gray matter; whereas, in the spinal cord, the white matter surrounds the central gray matter. White matter is involved in normal motor and sensory function, this tissue is responsible for learning and coordinating communication between different brain regions. Moreover, grey matter is involved in muscle control and sensory function (e.g., hearing, vision, memory, emotions, speech, decision making, etc).

Answer: A: OH-

Explanation:

Bases are substances that increase the concentration of OH- ions in water when they dissolve in it.

Answer:

The pH remains constant

Explanation:

The pH value of Mitochondrial matrix = 7.8 while the pH of the intermembrane space of the mitochondria = 7.0–7.4

The presence of the hydrogen atoms makes the mitochondrial matrix acidic and hence reduced the pH value but the pH of inner and outer matrix is maintained equal to each other thus as the H+ ion increases, the base concentration increases thereby pushing H+ to the inter membrane space and hence producing ATP.

Answer:yes and no there is no context just yes

Explanation:

Answer:

Due to changes occur in the protein structure.

Explanation:

The different types of mutants produced at the level of protein structure because mutation changes the protein structure of organism which leads to different types of mutant organisms. There were no mutants that produced no enzyme because enzymes are the most important part of the body in order to help the organism in their survival. These enzymes speed up the process of chemical reaction.

Answer:

2)A Dutch father-son team named Hans and Zacharias Janssen invented the first so-called compound microscope in the late 16th century when they discovered that, if they put a lens at the top and bottom of a tube and looked through it, objects on the other end became magnified.

3)While observing cork through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells. He had discovered plant cells! Hooke's discovery led to the understanding of cells as the smallest units of life—the foundation of cell theory.

Answer:

The cell model clearly shows all the processes involved, and it’s easy to understand, even if a person isn’t familiar with the process. The actual cell diagram doesn’t show all the organelles, so it’s an inaccurate representation of the cell. It also doesn’t show all the RNA involved in transcription and translation.
