Shallow groove on the surface of the cortex is called sulcus.

Cortex means the outer layer of an inner organ. The outer layer of the cerebrum is called cerebral cortex, where cerebrum occupies the biggest part of the brain. A human being has four lobes of the cerebral cortex which include temporal lobe, parietal lobe, occipital lobe, and frontal lobe.

Cortex has six layers of different types of neurons which are responsible for higher information processing and thinking. Cerebral cortex controls general movement, behavioural reactions, perception and visceral functions. We term the grooved layer as the brain itself.Cerebral cortex consists of large amounts of sulci and gyri(sulcus and gyri in singular). The number of gyri correlates to the processing ability of the animal.A man has big gyri compared to a rat.

Radda [10]

I think the correct answer would be D. In the process of petrification, a tree burning is not included. Petrification is a process that involves organic materials turning into fossils by replacing the original contents of a certain object with minerals.

Cell population growth can be represented by the number ______ with an exponent, where the exponent increases by ______ in each

ollegr [7]

Answer:

Cell population growth can be represented by the number 2 with an exponent, where the exponent increases by 1 in each generation.

Explanation:

As we know, every cell doubles after the process of cell division. Hence the cell population growth is represented by the number 2. The cell population growth is also known as the doubling time of a cell. The proliferation of cells is often written as:

Nt = N0 2tf

Where,

Nt is the number of cells at a particular time t.

N0 is the initial number of cells.

f is the frequency of cell cycles

Concentration cell based on the Ni2 -Ni cell reaction.

Alex73 [517]

Answer:

Explanation:

The missing diagram contained in this question is first attached in the image below.

The objective of this question is to determine how ions migrate when the cells are operating by assuming the solutions are composed of Ni(NO3)2.

From the information provided:

In this instance, the ions tend to move first from cathode to anode in terms of raising the concentration of Ni(2+) at the anode, resulting in the development of a dead cell. The initial concentration of [Ni(2+)] in the anode solution is 1.00 × 10⁻³ M, which gradually increases to 0.5 M, during which both the cathode and the anode possess the same concentration at the same point.

This causes Q(equilibrium constant) to equal 1 as well as log(Q) to equal 0, indicating that the cell is dead.

As a result, the cell will cease to operate, and nothing will migrate from the left to the right side.

Why should a woman be cautioned against taking acetylsalicylic acid to relieve pain in labor?

Ksenya-84 [330]

Aspirin, also known as acetylsalicylic acid, is a medication used to treat pain, fever, or inflammation. Taking aspirin regularly during pregnancy can affect your baby's heart or blood flow, so it's best to avoid aspirin unless your doctor recommends you take it. Your best bet for dealing with labor pain at home is to keep active until it's time to head to the hospital.
