FOR THE SECOND TIME-----Ughhh can someone answer this dang biology question I cant!!!!! I will mark you brainliest!!Referring to the graph, what phases together would account for approximately 25% of the time spent from a cell in the cell cycle?
A) M phase and S phase
B) S phase and M phase
C) G1 phase and M phase
D) G2 phase and M phase
Answer:
D. G2 phase and M phase
Explanation:
If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So, G1 phase and M phase would take up more than that, and we want 25% not 50+. The M phase and S phase would take up about a third, so no. The G2 phase and M phase takes up roughly 25% or, it's the closest to this.
differentiate between arteries and veins what is the importance of capillaries in the circulatory system.
Answer:
Arteries-1.Involved in carrying pure, oxygenated blood and nutrient-rich blood.
2.Consists of three distinct layers, which are rigid, thicker and highly muscular.
3.Located deep within the body.
4.Red in colour.
5.Carry blood away from the heart to various parts of the body.
6.High pressure, as the blood flows by the pumping pressure of the heart.
7.Comparatively higher oxygen level.
8.The level of carbon dioxide is low
9.Lumina is narrow
10.Valves are absent
11.Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc.
Veins-1.Involved in carrying impure, deoxygenated blood
2.Consists of three distinct layers, which are thin and collapsible.
3.Peripherally located closer to the skin.
4.Blue in colour.
5.Carry blood towards the heart from the various parts of the body.
6.Low pressure, as the blood flows by the capillary action of the veins.
7.Comparatively low oxygen level.
8.The level of carbon dioxide is high
9.In upward direction from the body tissues to the heart.
10.Lumina is wide & Valves are present.
11.Veins are less susceptible to diseases such as varicose veins.
Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.

Why do heart cells have different characteristics than skin cells???
Heart cells have different DNA than skin cells.
Heart cells reproduce by mitosis.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Answer:
Heart cells express different genes than skin cells
Explanation:
Cells contain instructions for their gene expression within stretches of DNA called genes, which is expressed and translated into protein.
Somatic cells are cells which contain the organism's chromosome number. They contain the entire karotype- and divide/ replicate through mitosis. In several stages of mitosis, DNA becomes condensed, is unwound and replicated, then packaged into two identical daughter cells.
All somatic cells start out undifferentiated (as stem cells). AFter the process of differentiation, they undergo changes in gene expression to become specific cell types, through processes like methylation and gain maturity.

The liquid is a pure substance because it is made up of elements
The liquid is an impure substance because it is inside a thermometer.
The liquid is a pure substance because it is made up of mixtures.
Answer:
b
Explanation:
DID IT
Mercury is used in thermometers to estimate temperatures. Liquid mercury composed of Hg atoms is a pure substance that consists of single elements. Thus, option B is correct.
What are pure substances?Pure substances are chemicals that are matter and have been known to have distinct chemical properties because of their constant and definite composition. The physical methods of separation can not be used to separate the pure substances.
The liquid mercury is a pure substance as it has been composed of only one type of elemental atom Hg. All of its composition has been carrying the Hg atoms uniformly that possess and exhibit the same chemical and physical characteristics.
Therefore, option B. the liquid mercury is a pure substance as it is made of the same type of element.

Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system
A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for support C. nitrogen-fixing bacteria and the roots of legumes D. pigs feeding at a trough
Answer:
A. red blood cells containing malaria
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.
.Which of the following lists contains only arthropods?
A
annelids, insects, myriapods CADA STAVI819 UAB
B.
arachnids, crustaceans, myriapods
С
crustaceans, insects. molluscs
D insects, myriapods, nematodes
Answer:
Arachnids, crustaceans, myriapods.
Explanation:
Arthropods are animals that form the phylum Euarthropoda. This phylum includes the arachnids, crustaceans, myriapods, and insects. The defining characteristic for an animal to be considered an arthropod is that it has to have an exoskeleton, meaning that the skeleton of the animal is acting as a shell to the body, covering it from the outside.
At present, all of the species of arthropods are small in size, though in the distant past there were speciemens that can be considered as medium-sized or even large. The exoskeleton has its advantages and disadvantages. An advantage is that it is very hard and it covers fully the internal organs, thus protecting them. A disadvantage is that it limits the size to which these animals can grow as the exoskeleton cannot support the weight of the body after certain point.

Organ systems maintain which of the following at
just the right
levels to support life processes?
a.) pH
b.) Carcinogens
C.) Temperature and pH
d.) Carcinogens and pH
Answer:
C.) Temperature and pH
Explanation:
Organ systems maintain the right temperature and pH levels to support life processes.
This is known as internal regulation or homeostasis.
Processes that support life requires some amount of fairly constant conditions for optimum level of metabolism to be attained. When the conditions are poor or in excess, reactions can greatly suffer. The ability of complex organism to maintain the right levels to support life processes is called homeostasis. pH and temperature are very important to all living organisms.Answer:

Explanation:
Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Global warming potential is defined as the ability of an atmospheric gas to contribute to increasing global temperatures and
anthropogenic climate change. Carbon dioxide is used as a baseline for global warming potential, with a GWP of 1. What best
explains why CFCs (chlorofluorocarbons) have a GWP
nearly 5000?
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.
Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[tex]\boxed {\boxed {\sf Enzymes}}[/tex]
Explanation:
Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat. Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.
So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.
