Wha does t mean for a membrane to be selectively permeable?
AOnly certain molecules are allowed to pass through
BThe membrane is rigidgad only alows water to pass through
CAll types of molecules are able to pass into the cell
DThe membrane is rigid and nothing can enter or leave the cell
Answer:
A
Explanation:
Answer: A
Selective means to chose something and permeable means a material or membranes that allows substances to pass through it so if something is selectively permeable then it only allows certain things can pass through. For example, only small molecules like water can pass through the cell membrane and larger molecules like carbohydrates cannot.

Is it possible for jellyfish to have autism
Answer: I believe the answer is no, as to see they have no brain.
Explanation: They have a basic set of nerves at the base of their tentacles which can detect touch, temperature, salinity etc. Since they don't have a brain, they depend on automatic reflexes in response to these stimuli! Catching prey is also a matter of chance. Lacking brains, blood, or even hearts, jellyfish are pretty simple critters. They are composed of three layers: an outer layer, called the epidermis; a middle layer made of a thick, elastic, jelly-like substance called mesoglea; and an inner layer, called the gastrodermis.

What was a negative consequence of humans being hunter-gatherers? A. they needed to stay in one location for food B. they cultivated their own food C. they had to move around to find food D. they had to have large families to help on the farm
Answer:
I am pretty sure it is c
Explanation:
It is the most logical sorry if im wrong
The statement which represents a negative consequence of humans being hunter-gatherers is that they had to move around to find food. Thus, the correct option for this question is C.
What do you mean by Hunter-gatherers?Hunter-gatherers may be defined as the type of person who considerably depends primarily on wild foods for subsistence. They are humans who do not practice agriculture for subsistence, but, instead, rely on what they can gather, forage, and hunt for their food supply.
The negative impact was on the animals who fed on those plants as they would have had much less food to eat. In addition, as their hunting skills became more efficient, hunter-gatherers hunted some animal species to extinction. Due to this continuous process, they had to move around to find food in other locations.
Therefore, the correct option for this question is C.

How is economics being used to solve environmental issues?
Explanation:
The environmental sciences have documented large and worrisome changes in earth systems, from climate change and loss of biodiversity, to changes in hydrological and nutrient cycles and depletion of natural resources. These global environmental changes have potentially large negative consequences for future human well-being, and raise questions about whether global civilization is on a sustainable path or is “consuming too much” by depleting vital natural capital (13). The increased scale of economic activity and the consequent increasing impacts on a finite Earth arises from both major demographic changes—including population growth, shifts in age structure, urbanization, and spatial redistributions through migration and rising per capita income and shifts in consumption patterns, such as increases in meat consumption with rising income (19, 20).

what process most directly allows parents to pass genes into offspring
Answer:
Sexual Reproduction
Explanation:
When two parents are involved in reproduction, it is referred to as sexual reproduction. When two parents pass on their genes to offspring, it allows for more mixing of genes and variation in the population. The prefix "a" in asexual reproduction indicates "without", and it only involves one parent budding or dividing to make an exact copy of itself. The processes of mitosis and meiosis refer to specific cell divisions necessary for copying genetic material, but they are not involved in the specific passing on of genes to offspring.

Which of the following atmospheric conditions are needed to create the winds?
I. Air masses with equal humidity
II. Air masses with equal temperatures
III. Air masses with different air pressures
- I and II
- I and III
- I only
- III only
Answer:
III only
Explanation:
took the test
The atmospheric condition which is required to create the winds is the air masses with different air pressures. Thus, the correct option for this question is D.
How is wind created?The Wind is created when the radiation of the sun warms or heats one-half of the atmosphere which stimulates the expansion of warmer air whose pressure is low as compared to cooler. The movement of air has occurred from a region of high pressure to a region of low pressure.
During the creation of the wind, humidity and temperatures are not directly involved. But the differences in air pressures are actively involved in the process which is initiated by the radiation of the sun on the atmosphere.
Therefore, air masses with different air pressures is an atmospheric condition that is required to create the winds. Thus, the correct option for this question is D.

what is the most likely effect of the poison? (Hint: Identify which enzymes have already done their jobs inside the bubble, and which haven't
The effect of the poison is to make the ligase enzyme stops working.
We can arrive at this answer because:
The ligase enzyme has the function of joining the old strand of DNA with the new strand that was produced by the DNA polymerase.In the diagram shown below, we can see that in part of the DNA molecule, the ligase managed to join the two strands of DNA, but part of these strands still does not join the new strand.We can conclude that the poison acted at this point in DNA replication, preventing the ligase from joining the two strands and causing the new strand to fail to adhere and was lost during the process.
The question above is incomplete, but its full version can be seen in the figure below.
