Explanation:
a cell with a single set of chromosomes
in humans contain 23 chromosomes
includes gametes
The stage of mitosis where the chromosomes line up
Answer:
Metaphase
Explanation:
Chromosomes line up at the metaphase plate, under strain from the mitotic shaft. The two sister chromatids of every chromosome are caught by microtubules from inverse shaft posts. In metaphase, the shaft has caught every one of the chromosomes and arranged them at the center of the cell, prepared to separate.
Answer:
It is metaphase.
Explanation:
In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.
A student looks at the daughter cells that result from a process of cell division. Which evidence would support that the process is meiosis? A. The daughter cells are larger than the parent cell B. The daughter cells are the same size as the parent cell C, the genetic material in the daughter cells is the same as in the parent cell D. The genetic material in the daughter cells is different than in the parent cell
Answer: C
Explanation: When daughter cells divide, they always pick up most of the genetic materials/features that the parent cell have.

Explanation:
Antibiotic resistant bacteria are becoming more and more prevalent, leaving us in desperate need of novel antimicrobial compounds to replace the drugs that are now obsolete in our hospitals and medical clinics. A high throughput screen of 700,000 compound library has allowed you to identify one molecule capable of killing extensively drug resistant tuberculosis at concentrations 1000X lower than currently used therapeutics. The only problem is, you don't know the molecular target. Develop an experimental strategy to identify the molecular target of your new antibiotic. Make sure to use some of the techniques described in the chapters covered throughout Units 1-6, and be creative. There isn't one correct answer!'
Answer:
Explanation:
We know the molecules equipped for killing broadly drug-resistant tuberculosis. This requires that we build up an experimental test system to distinguish the molecular target of your new antibiotic.
These steps include:
Gather proteomics data of tuberculosis and gather structural data of all proteins inside it.
At that point perform molecular docking with the molecule you as of now have.
This can yield the molecular target for the new antibiotic.

All materials are made up of only one part.
Answer:
Option B.
Explanation:
All materials are made up of smaller parts that cannot be seen without magnification.
Can the ecosystem survive without light? Why or why not?
Answer:
No
Explanation:
Because plants prepare their food form photosynthesis and sun light is basic element for that process to take place. So without sunkight the plants would die and due to their extinction herbivorous animals would die eventually and then the other animals depending upon herbivorous will also die due dissapearence of their food
Pls help this is due in an hour!!!!
Answer:
Throughout their life cycles, frogs have an important place in the food chain as both predators and prey. As tadpoles, they eat algae, helping regulate blooms and reducing the chances of algal contamination. Frogs are an important source of food for a variety of animals, including birds, fish, monkeys and snakes.

When certain molecules accept and then donate electrons, they also pick up H+ ions in the matrix, then release them into the inter membrane space.
As H+ diffuses back into the matrix through ATP synthase, its passage drives the phosphorylation of ADP to ATP. This process is called.............
A.Chemiosmosis
B.Electron Transport Chain
C. Synthesis of ATP
D.ADP phosphorylation
Which of the following best describes a population?

Explanation:
Justin wants to know how much gas his mother will save if he rides his bike to school rather than being driven in the car. For one month, Justin rides his bike to school. Every week, he asked his mother how much gas she put in the car. The next month, Justin had his mother drive him to school. Again, every week he asked her how much gas she put in the car. What could Justin do to improve this experiment?
Answer:
ask his mother?
Explanation:
Answer:
To improve the experiment, Justin should have created a hypothesis and could have repeated the experiment to see if the results were at least similar.
Explanation:
Hope this helps!

You are a scientist working on characterizing marine microbes that have a major role in the global nitrogen cycle. You finally culture the bacteria you are interested in and find it can grow at twice the rate that you expected, and you suspect it can make proteins more quickly than other bacteria. You want to better characterize genes involved in translation, particularly the enzymatic component of the ribosome. To do that, you must sequence which gene(s) involved in translation
Answer:
The correct answer would be - the 16S rRNA gene.
Explanation:
16S ribosomal RNA is a small subunit of ribosomes found in prokaryotic cells such as microbes. It is coded by the 16S rRNA gene that is used in constructing phylogenies again due to the slow rate of evolution.
This gene is suggested to be used as a molecular clock that is more reliable as it has sequences that show similar functionalities in distantly related bacterial lineages. It is the gene that produces protein more quickly than other bacteria.

Describe the conditions under which new species may arise.
Answer:
Explanation:i dont knowim so sorry
Answer:
New species arise through a process called speciation. In speciation, an ancestral species splits into two or more descendant species that are genetically different from one another and can no longer interbreed.

A salt marsh community includes egrets, gulls, and marsh crabs living together in a salt marsh. What does one female egret represent?
Answer:
It is a tool for keeping population in equilibrium state.
Explanation:
One female egret represents that she is a tool for the continuity of its breed or species because female egret lays eggs and reared their offspring in order to maintain its generation in that salt marsh area. These female egrets are the essential part of this salt marsh ecosystem due to the ability to control the population of other organisms through feeding behaviour. These female egrets helps in maintaining the equilibrium of the ecosystem by constantly producing baby egrets.
why progesterone is called pregnancy hormone????
Answer:
Progesterone isn't as important during normal menstrual cycles, but it is very important in pregnancy. It is the hormone which maintains the uterus lining and also avoids the menstrual cycle from taking place in order to prevent the baby from being aborted.
