Westkost [7]

Answer:

1) Cutaneous Anthrax

2) Inhalation Anthrax

3) gastrointestinal anthrax

Explanation:

The four types of Anthrax infection are:

1) Cutaneous Anthrax - In this type of anthrax, red spot is raised on the skin which increase with redness around it. The symptoms of this include headache, fever, vomiting, etc

2) Inhalation Anthrax - the symptoms of this type of anthrax include, headaches, flu, respiratory problem, coma, and severe cases death.

3) gastrointestinal anthrax - this cause due to the eating of contaminated meat which results in nausea,  diarrhea, abdominal pain, etc.

A mutation in a gene that controls mitosis in cells may cause? a) cancer. b) cystic fibrosis. c) albinism. d) meiosis.
harkovskaia [24]
The answer is <span>a) cancer.

</span><span>Cells must control mitosis (cell division) in order to maintain normal cell function. If something happens to the control of mitosis, the healthy cells will divide uncontrollably. These new cells are cancer cells and they are also out of control. They will continue to divide uncontrollably, so the mass of the cancer cells will grow.
</span>Regarding other choices:
- cystic fibrosis is an inherited disorder of lungs and digestive system,
- albinism is a congenital disorder characterised by the absence of pigment in the skin and hair,
- meiosis is cell division resulting in the reduction of a chromosome number in half.

Over-the-counter drugs commonly abused by teens and young adults include
SashulF [63]

Answer:

B

Explanation:

Any drug sold in the supermarkets, convenient stores etc  without prescriptions are called OTC-medication or over the counter drugs.

They are the group of drugs commonly abused  by young adults. Recommendation by  National Institute  on Drug Abuse is that , any  use of drug not related to medical purpose, but for mind-altering effects or arousal is regarded as an abuse. No doubt  these drugs are obtained over the counter because they are very easy to get, very cheap and legalized  by law to buy, thus easily accessible.

They drugs are high in contents which produces psychoactive effects when imbibed in over dose, and some may have damaging effects on the kidney and liver.

Other effects on the body physiology includes headaches, vomiting, nausea, seizures, tremors. etc.

About this much of the energy released from food molecules during catabolism is released as heat:______.
lorasvet [3.4K]

About this much of the energy released from food molecules during catabolism is released as heat: adenosine triphosphate (ATP)

The Adenosine triphosphate (ATP) is the source of the energy for the use and the storage at the cellular level. The structure of the ATP is a nucleoside triphosphate, consisting of the nitrogenous base (adenine), and ribose sugar, and the three serially bonded phosphate groups

ATP is synthesized in the mitochondria is the primary energy source for the important biological functions, such as the muscle contraction, the nerve impulse transmission, and the protein synthesis

In general, the main energy source for the cellular metabolism is the glucose, which is the catabolized in the three subsequent processes—the glycolysis, tricarboxylic and acid cycle (TCA or Krebs

Check all the functions that take place within the eukaryotic cytoplasm.
sesenic [268]

The cytoplasm is a fluid substance that fills every living cell which is enclosed by the cell membrane. This substance is mainly composed of water and proteins.

The functions that take place within the eukaryotic cytoplasm are diverse:

  • Location for most metabolic pathways. Except for the metabolic pahtways in cell nucleus and cytoplasmatic organelles, all metabolic functions (e.g., synthesis of biomolecules, growth, etc) occur in the cytoplasm.  The cytoplasm contain enzymes (i.e., proteins) to carry out different chemical reactions.

  • Location for organelles that house many of the metabolic pathways for the cell. For example, the synthesis of ATP (the energy coin of the cells) is carried out in the mitochondria, which are organelles found in the cytoplasm.

  • Location for the cytoskeleton that gives integrity to the cell. The cytoplasm contains all of the three types of filaments of the cytoskeleton (i.e., microtubules, actin filaments, and intermediate filaments) which provides structural support to the cells.

On the other hand, in plant cells, the cell wall is located outside the cell membrane.
