1. What is apoptosis and what does it have to do with cancer cells?
2. What is the purpose of the Bcl‑2 proteins?
3. What is and oncogene and what can we gain from studying them?
Answer:
1.Apoptosis in Cancer
The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation [2].
2.BCL-2 family proteins are the regulators of apoptosis, but also have other functions. This family of interacting partners includes inhibitors and inducers of cell death. Together they regulate and mediate the process by which mitochondria contribute to cell death known as the intrinsic apoptosis pathway.

Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them defeat the antibiotic, which then may increase their fitness.
Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that allow them to survive the antibiotic and reproduce may have higher fitness.

Plz answer I will mark u as brainly. Carla drew a diagram to compare the roles of oxygen and hydrogen in photosynthesis. Which label belongs in the area marked Y? Enters plant as a part of water Combines with carbon dioxide Is released into air through stomata Is stored in leaves for later use
Answer:
Option A, Enters plant as part of water
Explanation:
In the process of photosynthesis, water molecule is broken down into oxygen and hydrogen through photolysis.
Once the molecule is broken down , oxygen is released and hydrogen ion are used for initiating the further reactions in photosynthesis.
The following reaction occurs in photolysis-
2H2O -----> 4H+ + O2
Water is the most suitable subset among all.
Hence, option A is correct
Answer:
Not sure, but a good chance that it is released into air through stomata

Why would your heart rate increase or decrease to help maintain homeostasis when you exercise?
Answer:
The cardiovascular system helps to maintain homeostasis with respect to body temperature. An increased heart rate increases the delivery of blood to your skin. Increased blood flow to your skin and sweating causes dissipation of heat, and body temperature remains within normal limits.
Explanation:
Answer:
well here mate.
Explanation:
the reason i9s while exercising different exercises require different levels of energy therefor why you do push ups your heart rate will beat very fast depending on how long you have been doing them, and when you jog you are at a comfy speed there fore your heart rate stays low and calm.

What are 2 differences and similarities between these two processes?
Answer:
The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship.Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
Explanation:
The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.Both processes need carbon dioxide to produce the carbohydrates. Both processes also need an energy source to fuel the reactions. And, most important, both photosynthesis and chemosynthesis result in food for the organisms, which in turn becomes food for other organisms, supporting the circle of life.Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.

Which biome receives 200 to 400 cm of rain per year?
o deciduous forest
O temperate rain forest
taiga
grassland
Answer:
The correct answer would be - temperate rainforest.
Explanation:
The temperate rain forest is the annual is receives 200 cm to 400 cm per year. The annual precipitation is also up to 200 cm annually in this biome. It is coniferous and broadleaves are found.
The temperate rainforest is the biome that gets dense humidity and higher rainfall per year and the trees shed their old leaves every year and new leaves are found each year. The climate is usually mild and neither cold nor hot.

During protein synthesis, is DNA replication needed to start the transcription process? I always see these two processes together but I don't see how DNA replication is needed here. Thank you.
in protein sysnthesis, DNA is needed but not the replication of it. The DNA is used as a template for the mRNA (which will leave the nucleus and code for the protines). DNA replication is needed to conserve the genes but it isn't necessarily needed in protien synthesis
if this didn't make sense then i can elaborate on it :)

Rain washing oily runoff from a road into a river that runs alongside the road is an example of point source pollution or nonpoint source pollution?
Help pls.
Answer:
This would be an example of nonpoint source pollution.
Explanation:
The source of point source pollution is typically factories and powerplants, leading to more air and water transferred pollutants and becoming easier to track. Nonpoint source pollution is the opposite of point-source pollution, with pollutants being released in a wide area. Since the rainwater would be washing the oils and particles into the water, it would be considered runoff. Runoff is one of the leading causes of point source pollution. I hope this helps. ^_^

Explanation:
In May 2018, the Kilauea volcano on Hawaii's Big Island began to erupt, spewing lava over part of the island.
Which event are Hawaiians most likely to observe first in the areas covered by lava?
A. Mosses will grow in thin, rocky soil.
B. Lichens will grow on the cooled lava.
C. Trees will grow in thick, rich soil.
D. Grasses will grow in soil with organic matter.
Primary succession occurs after the occurrence of a severe event that leaves nothing but rocky surfaces. Option B. Lichens will grow on the cooled lava.
What is succession?
The succession term refers to colonization and subsequent changes.
Colonization has been defined as the sequence of events that conduce to the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.
Succession refers to changes produced in the composition and structure of communities after a perturbation. There are different grades of succession according to the perturbation intensity.
What is Primary succession?In primary succession, the perturbation is so intense that it eliminates all the life forms in the area.
It is the sequence of species appearance in an exposed area that has not been influenced by any other species or community before.
In these cases, the rock gets exposed but it can not be colonized directly. The new area needs to suffer erosion and different chemical and physical processes that fragment, degrade and dissolve the rock to make colonization possible.
Primary succession occurs after severe events affecting a region, such as a retreating glacier, a volcanic activity, or an intense fire that leave nothing but the exposed rock.
After the disturbance, the order of the living beings establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space.
Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses.
Grasses and pioneers keep modifying the ground and making it better with time.
Habitat modification keeps on going while new species establish. They produce shadows and alter the temperature, and humidity, fertilizing the soil.
Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources.
This sequence continues until there is no more facilitation, and the communities reache a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
In the exposed example, the severe event affecting the Hawaii's Big Island was a volcanoe eruption.
The most likely event observed first in the areas covered by lava would be Lichens will grow on the cooled lava. Option B

Imagine you are a population ecologist who is starting a campaign to control invasive species in your community. Write 3-5 sentences about what you would tell members of your community who come to a meeting to learn about invasive species.
Answer:
This is what I would say:
Hello, today I will talk to you about invasive species and why they should be stopped, invasive species are bad for the environment because they destroy other creatures, like if the native species think that it's prey and decide to eat it; it might harm them. For example, if there were trees in a certain environment and an invasive species came along every creature would get hurt because those trees are very tall and they stop sunlight from reaching the ground so that would help to stop invasive plants from growing but if an invasive species of beetles came along they would eat the trees and kill them making sunlight reach the ground. Then it would help the invasive plants to grow, and what would the invasive species of plants do you ask? They would harm the creatures because there are herbivores and they eat plants and since they might think that the plant is toxic because they look like a toxic plant in that environment they will starve and die. Little by little the animals would get harmed because predators eat the herbivores and if there's no food for them they will die, so you see a lot of creatures would get harmed if we don't stop invasive species.
P.S. maybe you should change the words a little because I used this in previous work.
