Answer:
The correct answer is - Bcl2 proteins are part of the extrinsic apoptosis pathway.
Explanation:
The Bcl-2 family group of proteins that are known to either promote or inhibit the process of apoptosis by regulating the mitochondrial membrane potential. Bax and Bak are Bcl-2 proteins, act as pro-apoptotic proteins which oligomerize to result in forming pores in the membrane of the mitochondria.
These pores lead to the release of cytochrome c to the cytoplasm. Bcl-2 protein is an anti-apoptotic protein that inhibits the oligomerization of Bak and Bax.

Please help me with this! *30 *points Picture included
Answer:
1.) The first picture is mitochondria and the second picture is chloroplast
2.) The second one is only in plants
3.) The first one is found more commonly in animal cells
4.) Glucose & oxygen goes into #1 and releases ATP energy and water & carbon dioxide (waste) during cellular respiration
5.) Sunlight and water goes into #2 and releases oxygen (waste)
6.) The waste product from mitochondria is what the chloroplast needs to perform photosynthesis and vice versa for mitochondria where the waste product from the chloroplast is what mitochondria needs to make ATP energy
7.) They both have folds and membranes because this is how energy is transferred from one place to another.

How do consumers obtain the carbon that they need for their life processes?
They breathe it in from the surrounding air.
They break down the plants and animals they eat.
They absorb it from the surrounding soil.
They absorb it from water through their pores.
Explanation:
They break down the plants and animals they eat
this is because, plants absorb carbon from the atmosphere to grow in the process of photosynthesis, then consumers obtain their food from plants hence obtaining carbon
Answer: B. They break down the plants and animals they eat.

Hippopotamuses live in Africa’s rivers and lakes. They’re herbivores and coexist with other herbivores and carnivores. Which action could lead to a decrease in the number of hippos?
Answer:
If any of the other carnivores are predator they might eat the hippos. If the other herbivores population incresses there food supply may drop. If there is a drought there habitat will be in danger. Pouchers are also a threat to this animal.
Explanation:
In maize, yellow kernel color is dominant to white, and wrinkled kernel shape is dominant to the smooth form. Considering both of these traits jointly in self- fertilized dihybrids, the progeny appeared in the following numbers: 193 white, genes assort independently? Support your conclusion using appropriate statistical analysis. wrinkled; 184 yellow smooth; 556 yellow, wrinkled: 61 white smooth
Answer:
yellow, wrinkled are high in population whereas white smooth is lower in population.
Explanation:
Due to self-fertilized dihybrids, the offspring are yellow wrinkled, hybrid and white smooth. 556 yellow, wrinkled are high in population because of the dominant allele while on the other hand, 61 white smooth are obtained and less in number due to recessive nature that comes very little in the population. 184 yellow smooth and 193 white, wrinkled are the hybrid offspring that has both different characteristics from their parents.
Fertilizer sacks have a three- number value called the NPK value written on them. What does the NPK stand for (18-24-12 written on the bag)?
Answer:
it's a label number
Explanation:
Every label carries three conspicuous numbers, usually right above or below the product name. These three numbers form what is called the fertilizer's N-P-K ratio — the proportion of three plant nutrients in order: nitrogen (N), phosphorus (P) and potassium (K).
What is the likely cause for the Cheetah losing genetic diversity?
Answer: Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction, which is reducing the size of their populations. Cheetahs' own genes also pose a challenge to their continued survival

sexual reproduction drives
a)meoisis
b) genetic symmetry
c) reproductive strategies
d) genetic diversity
Answer:
a) Meiosis
Explanation:
Meiosis is a form of cell division that occurs in sexually reproducing animals' germ cells and is utilized to create gametes such as sperm and egg cells. It takes two rounds of division to produce four cells, each with only one copy of each chromosome.
Scientists have developed a new type of margarine that contains plant ingredients. They expect that the margarine will lower blood cholesterol levels. They want to test their hypothesis by comparing the blood cholesterol levels of people who will consume the new margarine with those who will consume regular margarine for a few days. Both groups of people will know which type of margarine they are to consume. Which type of research design will the scientists consider
Answer:
intervention study
Explanation:
The intervention study or research helps to examine the effects of an intervention of an outcome of interest. The main purpose of this type of study is to endenger the desirable of the individuals in need.
Such studies are often prospective.
In the context, scientist who have developed a new margarine containing plant ingredients. The scientists wanted to test the hypothesis whether consuming this new margarine lowers blood cholesterol in the body or not. They gave people to consume the margarine and is doing the research study. Such a research design is called as the intervention study.

The ___ in an experiment is the factor that is being
changed, or tested.
- control group
- dependent variable
- independent variable
- constant
Answer:
Independent Variable
Explanation:
The independent variable is what we are changing or what is being tested.
The control/constant group is when you do not change anything and you want to see how the object acts under normal conditions.
The dependent group is what you are measuring. (aka your data/results)

Ethan began making a model to show the processes which resulted in the formation of oceans
Which of the following would be the next step in the process?
Crust is broken down
Earths crust moves
Earths plates meet
Sea floor spreading
The next step in the process is sea floor spreading. The correct option is D.
What is sea floor spreading?Tectonic plates, which are huge chunks of the lithosphere of the Earth, split apart from one another during the geologic process of seafloor spreading.
The oceanic basin is the result of sea floor spreading.
The ocean crust and its basins are formed when the sea floor spreads and separates after the basin has been filled with water.
All of these result from various plate interactions within the planet.
New ocean floors are created by volcanic activity at spreading centers at divergent borders after the crust has developed and accumulated water.
The production of fresh crust occurs close to the margin, and subsequent crusts push against and away from it. Ocean basins are created by the development of new ocean floors.
Thus, the correct option is D.

What would be considered a quantitative observation
Answer:
height of radish seedlings is measured.Quantitative observation is a method of collecting objective data that is largely focused on numbers and values — the phrase means "related with, of, or portrayed in terms of a quantity." Sending out surveys, questionnaires, or polls is a common method of quantitative observation.
quantitative observation include age, weight, height, length, population, size, and other numerical values while, qualitative observation are color, smell, taste, touch or feeling, typology, and shapes.

DNA's genetic information is copied to form ___ RNA, which then delivers it to the ___ where protein synthesis occurs.
Answer:
DNA's genetic information is copied to form mRNA, which then delivers it to the ribosome where protein synthesis occurs.
Explanation:
During transcription, RNA polymerase uses a single-stranded DNA template to synthesize a complementary strand of RNA. The mRNA then travels from the nucleus to the cytoplasm where ribosomes are found. Ribosomes are structures that are responsible for making proteins.

A cell membrane is very specific about what it allows to cross.how does this help the cell?
Answer:
The cell membrane is selectively permeable . It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all. Some small molecules such as water, oxygen and carbon dioxide can pass directly through the phospholipids in the cell membrane

Explanation:
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
The major purpose of mitosis is for growth and to replace worn out cells.
