Which phase of Mitosis is pictured below? *
Answers
Answer:
Telophase
Explanation:
this is the final phase of mitosis. which is why there is two cells pictured. mitosis is almost finished.
The phase of mitosis that is mentioned in the picture given below is known as Telophase.
What is Mitosis?Mitosis may be defined as a type of cell division that significantly leads to the production of two daughter cells from a parental cell. These daughter cells are genetically identical to the parental cells. They are usually diploid in nature.
During the termination of mitosis, telophase is the stage where two new nuclei form around the separated sets of daughter chromosomes. During this phase, two sets of daughter chromosomes reached opposite poles and converted into chromatin thread. The Nuclear membrane form round and the nucleolus reappear.
But it all initiates with the process of interphase that duplicates the amount of DNA which further gets divided into two daughter cells.
Therefore, telophase is the phase of mitosis that is mentioned in the picture given below.

Describe the importance of regulating blood glucose concentration.
Answers
Answer:
In order to play a crucial role in controlling blood sugar levels, all hormones act in balance. Blood sugar levels can spike or drop if the level of one hormone is higher or lower than the ideal range. Insulin and glucagon, together, help sustain a state called homeostasis in which conditions stay steady within the body.

Which statement explains how the circulatory system and the respiratory system work together to maintain homeostasis? Group of answer choices Veins carry blood away from the heart and deliver it to the organs. The lungs eliminate oxygen and exchange it for more carbon dioxide which is circulated. The blood pumped by the heart is transported to different parts of the body to deliver oxygen. Arteries carry blood towards the heart to increase its oxygen content.
Answers
Answer:
The blood pumped by the heart is transported to different parts of the body to deliver oxygen.
Explanation:
Homeostasis is a process whereby living cells maintain a stable internal environment despite changes in their external environment. One way cells perform homeostasis is by ensuring oxygen gas, which is required for cellular respiration, reaches all the cells. However, the circulatory and respiratory systems work hand in hand to fulfill this.
The respiratory system brings in oxygen present in air, which is then carried by a pigment in the blood called haemoglobin, to every part of the body. Hence, respiratory system brings in the oxygen gas while circulatory system ensures the oxygen gas is everywhere in the body.
Answer:
The blood pumped by the heart is transported to different parts of the body to deliver oxygen.
This diagram shows the menstrual cycle.
Explain whether the
female is pregnant.
Please explain why because I’m struggling.
Answers
Answer:
According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.
Explanation:
The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.
During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.
In the case of a pregnant woman:
Estrogens continue to increase after ovulation, produced by the ovaries and placenta. Progesterone also increases its levels, as it is a hormone produced by the ovaries and placenta. Hormone human chorionic gonadotropin (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.The diagram represents the normal cycle of a woman who is not pregnant.

a segment of dna has 320 nitrogen bases. if 40 of them are cytosine, how many are thymine
Answers
Why? - 320 Nitrogen bases.
Cytosine = 40, Cytosine = Guanine.
Therefore Guanine = 40.
320 - 80(Cytosine and Guanine)
240.
Adenine and Thymine = ?
Adenine = x and Thymine = x.
2x = 240.
X = 240/2
X = 120.
Adenine 120, Thymine = 120, Cytosine = 40 and Guanine = 40.
Scientists have discovered a new type of organism. To assign the organisms to a domain and a kingdom, which of the following is MOST important for the scientist to know?
Options
A- The organisms reproductive rate
B- The organism cell structure
C-The organisms population size
D-The organism social behavior
Answers
B- The organism cell structure
Explanation:The options you can rule out:
A- The organisms’ reproductive rate isn’t important since it’s just telling how fast the organism can grow, and it doesn’t provide information on where to assign it to a domain and kingdom.
C- The organisms’ population size of the organism isn’t important since it just shows how many there are, but it doesn’t provide information on where to assign it to a domain and kingdom
D- The organisms’ social behavior can be important (since it’s talking about how the organism acts and behaves toward other organisms, but it isn’t important on where to assign it to a domain and kingdom
Hence,
If scientists discovered a new type of organism, Option B: knowing the organism cell structure is most important, because it goes in dept on what the specific formation of the organism. Looking at the cell structure provides information on what where to assign is to a domain and kingdom.

Explain why light waves can travel through space, but sound waves cannot.
Answers
Answer:
In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this medium. ... Radio waves travel perfectly fine through a vacuum because they are a type of electromagnetic wave (light), and electromagnetic waves do not need a medium to travel through. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum. ... Light waves can be polarized, but sound waves cannot.
Explanation:
hope this helps have a good day :) ❤
Answer:
sound needs something to bounce back in order for it to be able to come back to your ears so in space where its a bunch of nothingness tht is not possible
Explanation:
a more detail explanation
Light can travel in vacuum but sound cannot. This’s because sound waves are vibrating waves (also called pressure waves ) travel by physical contact of molecules. Sound can travel in air, metals like steel or aluminium. Light speed is constant. But in case of sound denser the medium faster the speed
why do you think bacteria become resistant over time ?
Answers
Answer:
Because their DNA mutated
Explanation:
Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs become resistant. Examples of Defense Strategies for Germs

In Black Angus cattle, the color black is what type of genetic trait?
recessive
incomplete
dominan
genotype
Answers
Answer:
dominant
Explanation:
The "gene" of an organism consists of two alleles. One allele comes from each parent. A genetic trait is said to be "dominant" even if there's only one copy of dominant allele present; however, a genetic trait is said to be "recessive" if there are two recessive alleles present.
In Black Angus cattle, the dominant color is "black." They are even named after their color. The recessive trait is "red." In order for a Black Angus cattle to be red, it needs to have two alleles for the recessive trait (red). However, it is easy for the cattle to be black as long as it has one allele for the dominant trait.

A gene is a segment of DNA witch codes for specific trait.
Explanation:
DNA is the molecule that contains all the genetic information of living beings, which is used for the synthesis of proteins, that will serve to give structure and function to these organisms.
Each DNA molecule forms a chromosome, and segments of the DNA of that chromosome contain the information that constitutes the genes. Each gene formed by a fraction of the chromosome's DNA encodes the synthesis of proteins that define specific structural or functional traits.
