A human cell that has 46 chromosomes would have __ daughter cells that each have __ chromosomes after mitosis.
Answer:
2 daughter cells, 46 chromosomes
Explanation:
Mitosis is reproduction of somatic cells, or body cells. It's end product will always be 2 daughter cells, each identical to one another, therefore meaning, it will also have the same number of chromosomes!
Answer: one daughter cells and each have 23
Explanation: mitosis is the first then meiosis

what is the four chambers for the heart?
Answer:
The heart has four chambers: two atria and two ventricles.
Explanation:
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
Answer:
The four chambers of the heart are the Right atrium,Left atrium,Right ventricle and Left ventricle.

How can students in the photograph use the net to sample the invertebrates in the river.
Answer and Explanation:
Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.
There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.
Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.
Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.A typical virus is made up of 2 parts. Check all that apply.
A) Golgi Body
B) Nuclear envelope
C) Nucleic Acid
D) Capsid
Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.
Which of the following is a possible consequence associated with prolonged exposure to lead?
A) increased occurrence of delinquent behavior
B) increased occurrence of ADHD
C) increased occurrence of depression
D increased occurrence of obesity
Answer:
The answer is A. increased occurrence of delinquent behavior
Explanation:
edge 2021
A possible consequence associated with prolonged exposure to lead is the increased occurrence of delinquent behavior.
What are the effects of prolonged exposure to lead?Prolonged exposure to lead causes various severe diseases like reduced fertility, high blood pressure, heart diseases, kidney diseases, etc.
Lead is considered heavy metal which affects the health and psychology of humans to a large extent.
It increases the occurrence of delinquent behavior which means an act of criminal cases mostly carried out by adult people.
These delinquent behaviors are rapidly increasing due to the intake of drugs that contains a high amount of lead in it.
Therefore, a possible consequence associated with prolonged exposure to lead is the increased occurrence of delinquent behavior.

What is the function of erythrocytes?
What is the term for all the components of the blood?
What is blood?
Answer:
1. The main physiological role of red blood cells (RBCs), or erythrocytes is to transport of gases (O2, CO2) from the lung to the tissues and to maintain systemic acid/base equilibria. In addition, RBCs are well equipped with antioxidant systems, which essentially contribute to their function and integrity.
2. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.
3.Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

A grow more corn to produce ethanol
B. build more nuclear power plants
C. find and burn new sources of oil and coal
D. improve energy efficiency and reduce energy waste
Answer: D
Explanation: just took the quiz
The best solution that meets the energy demands while protecting the environment is to improve energy efficiency and reduce energy waste. Thus, the correct option for this question is D.
What is the Environment?The environment may be defined as a sum total of all forms of living and non-living elements and their consequences that significantly influence human life. It includes biotic and abiotic factors. The term environment is first given by Carlyle.
The protection of the environment requires a lot of actions by humans and the cooperation of other living organisms as well. All these actions impact the protection of the environment and improve energy efficiency along with the reduction in energy waste.
Therefore, improving energy efficiency and reducing energy waste is the best solution that meets energy demands while protecting the environment. Thus, the correct option for this question is D.

what measures to be taken in an operating room
Answer:
infection control- clean equipment to prevent spread of germs
All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation
Everything needs to be sterile
All instruments need to be inspected for any signs of contamination after the sterilisation process
Shoes from outside should never be worn inside an operating room
Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment
The surgical mask was introduced over a century ago. Its continued use is controversial as evidence is not conclusive that wearing a mask reduces postoperative infection. Wearing a mask, however, does protect the practitioner from contact with body fluids

What is the source of most salt in the ocean?
A.fish
B.human activity
C. Wind
D. Rocks on land
Answer:
D. rocks on land
Explanation:
Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.
Answer:
Option D Rocks on land
Explanation:
Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.
