Answer:
Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.
Explanation:

Answer:
A, D, and E is correct
Explanation: I took the test and got this one correct.
The items that are inferential statistics among the options would be:
Give the likelihood of data occurring by chanceTell you whether to call your mother about your resultsGive a measure of statistical significanceThis is largely due to the fact that inferential statistics refer to the branch of statistics that draws conclusions from a set of data. It is as opposed to descriptive statistics which focus on summarizing, describing, arranging, and or categorizing data in such a way that trends are shown at a glance.
Statistical parameters such as mean, mode, and median only measures attributes of data relating to the measure of central tendencies. Data summary is purely descriptiveHence, the items selected are those that are conclusive and not descriptive.

Which of the following might be an adaptation for a predator? AS SOON AS POSSIBLE NEED HELP PLS THX
Answer:
we need the answers
Explanation:
Answer:
Many predators have adaptations that help them survive in the wild. For example, the snake shown below has camoflauge coloring to look like its surroundings. This gives it the element of surprise when going to attack its prey. These adaptations help the predator in hunting for food. Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws. The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

List at least two variables that might influence the rate of cellular respiration.
Answer:
Answer below !
Explanation:
1) Oxygen Concentration
2) Temperature
3) Glucose Availability
Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability

8. im not sure abt this one, sry :(
9. yeah, true
10. c
Explanation:
Pro phase is the starting stage of the division where the cell division begins. Spindle fibers are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.
What is synapsis ?It is defined as the stage in which the pairing of the homologous chromosomes take place.
Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.
Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.
In meiosis crossing over takes place in anaphase 1.

Which health factor is an individual unable to change?
A-nutrition
B-environment
C-inherited genes
D-cholesterol levels
Answer:
C-inherited genes
Explanation:
The health factor that an individual is unable to change is inherited genes, which is in Option C, as inherited genes are passed down from parents to their offspring and can influence an individual's health.
What are inherited genes?Inherited genes are a fundamental aspect of an individual's biology that they are born with and cannot change. These genes provide the blueprint for the development and functioning of various systems in the body, including the immune system, cardiovascular system, and nervous system. Some genetic traits can increase an individual's risk of developing certain diseases or conditions, while others may protect against certain health problems. While individuals cannot change their inherited genes, they can take steps to manage their health based on their genetic risk factors.
Hence, a health factor that an individual is unable to change is inherited genes, which is in Option C.

One result of climate change is that ocean temperatures are increasing. If the temperatures continue to rise, what effect will that have on the oceans’ ability to retain CO2? How might this change affect the atmosphere? THIS IS SCIENCE WOULDNT LET ME SELECT IT
Answer:
See explanation
Explanation:
There is an equilibrium that exists between the carbon dioxide in the air and the carbon dioxide in the oceans. The temperature of the water affects its ability to hold carbon dioxide.
Hence, as the global temperature continues to rise and the water becomes warmer, its ability to hold carbon dioxide decreases. When this happens, the gas exchange across the air-ocean boundary is affected. There is now too much CO2 in the atmosphere owing to the disturbance of its air- ocean exchange equilibrium leading to more rise in temperature due to global warming.

Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm just curious. (didn't mean to sound creepy). thank you so much.
Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.
At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.
High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."
