Answer:
C
Explanation:
The one that always contain DNA as the main genetic material is cell nucleus. The correct option is C.
What is genetic material?The genetic material is the molecule that contains genes and is passed down from parents to children. It contains instructions for the growth and function of living organisms.
DNA and RNA are the two main types of genetic material. DNA is stored in the nucleus of eukaryotic cells, which have a nucleus and membrane-bound organelles, and is wrapped around round proteins called histones. DNA is ended up finding in the cytoplasm of prokaryotic cells.
A virus is composed of a core of genetic material surrounded by a protein-based protective coat called a capsid.
Viruses have either RNA or DNA as their genetic material, but neither. Single-stranded or double-stranded nucleic acid
Thus, the correct option is C.

Explanation:
Logistic regression is also vulnerable to overfitting. It cannot be applied to a non-linear problem. It will perform poorly with independent variables which are not correlated to the target and are correlated to each other.
What can be used to measure the rate of photosynthesis
Answer:
the answer it at the bottom
Explanation:
Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening.
Release of O2: The amount of O2 produced during photosynthesis can be measured.
Most pneumonia infections are caused by a virus or bacteria. What characteristic could scientist use to distinguish an infection caused by bacteria from an infection caused by a virus? Group of answer choices The bacteria would grow by itself outside the person. The virus would have DNA. The bacteria would make another person sick. The virus would have proteins.
Answer:
The bacteria would grow by itself outside the person
Explanation:
The bacteria would grow by itself outside the person. - this is correct. Bacteria are independent organisms that do not need other cells to replicate. However, viruses require the cell's machinery to divide and cannot survive independently
The virus would have DNA. - Both bacteria and viruses have DNA (or the virus might have RNA)
The bacteria would make another person sick. - Both viruses and bacteria could make another person sick
The virus would have proteins - Both viruses and bacteria have proteins

Answer:
Okay, I got this from google and my notes but the cells inside of a cell membrane are composed primarily of fatty-acid-based lipids and proteins.
Explanation:
Membrane lipids are principally of two types, phospholipids and sterols (generally cholesterol). These membranes are composed primarily of phospholipids and proteins and are typically described as phospholipid bi-layers. They also contain cholesterol in the phospholipid bilayer.

4 (As electrons move down the ETC, a H+ gradient is made), 2 (The Krebs cycle produces ATP, NADH and CO2), 5 (H+ pass through the ATP synthase to make ATP), 3 (NADH gives electrons to the ETC), 1 (In glycolysis, glucose is split into two pyruvate and makes some ATP)
In glycolysis, glucose is split into two pyruvate and makes some ATP. (GLYCOLYSIS)The Krebs cycle produces ATP, NADH and CO2. (KREBS CYCLE)NADH gives electrons to the ETC. (ELECTRON TRANSPORT CHAIN)As electrons move down the ETC, a H+ gradient is made. (ETC)H+ passes through the ATP synthase to make ATP. (ATP SYNTHASE)Explanation:
The correct steps are as follows:
NADH gives electrons to the ETC.The Krebs cycle produces ATP, NADH and CO2.In glycolysis, glucose is split into two pyruvate and makes some ATP.Ht pass through the ATP synthase to make ATP.As electrons move down the ETC, a H+ gradient is made.What is glycolysis? Glycolysis is the process in which glucose is broken down to produce energy. It generates two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms.Thus, these are the correct order.

Answer:
1. For generating healthy cells to form replacement organs like brains
Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.
What is stem cell?Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.
Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.
Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.
This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.
Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.
Thus, the correct option is 4.

The main components of the plasma membrane contain hydrophobic and hydrophilic regions that give the membrane selective permeability. Which of the following is the
main component that creates the hydrophobic and hydrophilic regions? (3 points)
a. Cholesterol molecules creating membrane fluidity
b. Carbohydrates for cell recognition
c. Glycolipids containing hydrophobic lipid portion
d. Phospholipids containing hydrophobic fatty acids tails
Answer:
The main components that creates the hydrophobic and hydrophilic regions of the plasma membrane are phospholipids containing hydrophobic fatty acids tails.
Explanation:
Phospholipids are the main component of the cell membrane —lipid bilayer— and responsible for its selective permeability. Each phospholipid is composed of one glycerol molecule, which forms the head, and two fatty acid tails, plus one phosphate molecule.
In the lipid bilayer, the phospholipid heads are oriented towards the surface, while the tails are located inside, allowing interaction with both polar and apolar molecules.
The hydrophilic regions of the membranes are in contact with the liquids of the extracellular and intracellular spaces, while the hydrophobic region is inside the membrane, limiting the passage of polar molecules or ions.
The other options are not correct because:
a. Cholesterol molecules are part of the membrane, but are not responsible for the hydrophobic and hydrophilic regions.
b. Carbohydrates for cell recognition do not determine membrane permeability.
c. Glycolipids, like integral proteins, are part of the membrane, but do not determine the polarity of the regions.
