Explain how different types of cells help organisms live and grow
all living things can be organized into different levels. organelles are suspended in cells that make up tissues, which then make up organs. these can be grouped into organ systems within whole organisms.
however, for single-celled organisms (prokaryotes)that lack tissues, organs or organ systems , their organisation starts with organelles and just ends at cells
Oxygen is taken from the water by
Explanation:
Humans use their lungs to inhale oxygen from the air. But worms, fish, crabs and other underwater animals use gills to get oxygen from the water. As water moves across an animal's gills, oxygen is removed and passed into the blood. Gills work better when there is more oxygen in the surrounding water.

Above is a bar graph showing how the average family uses water. Fresh water is a vitally important resource and its supply is limited. You want to try and help conserve this resource by cutting the usage of one of the fixtures above in half.
Answer:
We can't see the bar graph but showers use a lot of water so my guess would be cutting back on the time spent in the shower.

3 Name the gas that enters the leaf when the stomata are o
Answer:
guard cellsmonocots: evenly distributed, dicots: more dense on lower leaf Carbon dioxideExplanation:
Stomata are pores in the leaf surface of plants. they regulate the exchange of moisture and gases in plants. They open at night for the exchange absorption of Carbon dioxide and expulsion of Oxygen, while closing at the middle of the day to prevent evaporation of moisture or water in transpiration. These pores are opened or closed depending on the state of the two surrounding guard cells.
The somata are found on both the upper and the lower leaf surface. in dicots, the stomata are noticeably denser on the lower leaf surface, while they are evenly distributed on both leaf surfaces on monocots.
How does a seedling emerge from the ground?

The seedling forms a hypocotyl hook that pushes through the soil. Once the seedling reaches the light, the hook opens to create a straight seedling. The cotyledons function as the repository for food reserves in the seed.

Assign characters to the readers in your group.
Find a section in the novel with lots of good dialogue.
Find a section in the novel with lots of sensory details.
Assign lines and sentences to readers in your group.
Answer:
Find a section in the novel with lots of good dialogue.
Explanation:
Firstly, you can't assign characters or lines to the readers in your group for the first step. You need to search for a section that has good information to start it off with. Then, you can proceed to assigning whatever you like.
1. Assign characters to the readers in your group. THIS SHOULD BE THIRD since you've have already found some good dialogue and details on what to do. With that being said, it's now necessary to assign your characters. #3
2. Find a section in the novel with lots of good dialogue. THIS SHOULD BE FIRST as you need to start off with finding some good dialogue and descriptions as your "base".
#1
3. Find a section in the novel with lots of sensory details. THIS SHOULD BE SECOND as you need to find good dialogue in order to even find sensory details. Good dialogue will contain plenty of sensory details.
#2
4. Assign lines and sentences to readers in your group. THIS SHOULD BE FOURTH since you need characters to even assign lines and sentences in the first place.

Where homo erectus part of the neolithic revolution
In addition to having a more contemporary and body proportions, H. erectus was the first species of human to have a flat face, a prominent nose, and perhaps minimal body hair coverage.
Though there is little doubt that brain size has increased compared to ancestral species, capacity varies greatly depending on population. The size disparity between males and females in H. erectus may have been relatively small (i.e., there was less sexual dimorphism), which may have indicated monogamy in keeping with patterns seen in other primates. Although it is hypothesised that they interacted with one another using some form of proto-language, it is unknown whether H. erectus had the anatomical capacity for speech.
The Pleistocene archaic human species H. erectus, which means "upright man," first appeared about 2 million years ago. It is now extinct. Several human species, including H. heidelbergensis and H. antecessor, seem to have diverged from H. erectus, with the former being largely accepted as the ancestor of Neanderthals, Denisovans, and modern humans. Among the first recognisable representatives of the genus Homo are its specimens. The first known ancestor of modern humans, H. erectus, had a continental range that stretched from the Iberian Peninsula to Java.

A mutant E. coli strain does not express lacZ, even in the presence of lactose. What is a possible genotype of the cells?
Answer:
The answer is "[tex]\bold{lacI^{+} lacP^{+} lacO^{+} lacZ^{-} lacY^{-} lacA^{+}}[/tex] "
Explanation:
In this question, the prescribed mutant E. Coli does not express the lacZ gene, so beta-galactosidase doesn't quite exist. Therefore in a particular strain, there is also the potential of lacZ– and that only the genetic makeup indicates its production of lactose. Therefore the above-mentioned option is correct.

What helps make different types of carbohydrates?
Answer:
glycosidic bonds between monosaccharides that combine to form polysaccharides
Explanation:
The building blocks of carbohydrates are individual monosaccharides (i.e., sugar molecules), such as glucose, fructose, glucuronic acid, galactosamine, glucosamine, etc. These individual monomers of carbohydrates bond to form polysaccharides such as cellulose and starches. Monosaccharides form glycosidic bonds with an alcoholic OH group of a second monosaccharide to form a disaccharide (for example, lactose), and then these larger molecules bond together to form either linear or branched polysaccharides. Starch, for example, is a polysaccharide composed of monomers of glucose molecules.

Explain the three states of water and how it changes state. Use terms melt, boil, sublimation, evaporation, deposition.
-this is science-
water can exist in three states; liquid, solid and gases.
Explanation:
At temperature below zero degree Celsius, water exists as a solid but as it absorbs temperature from Its surroundings, it undergoes melting and turns into liquid water. More application of heat makes it boil leading to the evaporation and vapourisation of water molecules( note: evaporation occurs at all temperature).

What two structures surround cells?
Answer:
Cell membrane surround cells, but cell wall is an extra covering outside plant cells, made up of cellulose
A cell plasma membrane and cell wall surround the eukaryotic cell.In the animal cell, there is a plasma membrane. In the plant cell, both the plasma membrane and cell wall are present.
What is the plasma membrane?The plasma membrane is the outermost covering of the cell that restricts the movement of molecules across the cell. In eukaryotic cells, the plasma membrane is hydrophobic by nature. It has carriers and ion channels in it. The plasma membrane has proteins, glycolipids, glycoproteins, etc. Apart from this, the plasma membrane of animals has cholesterol.
The plant has a cell wall outside of the plasma membrane. The cell wall is made up of cellulose. The polysaccharide cellulose is composed of glucose monomers.The cell wall is more rigid than the plasma membrane. The cell wall is present in some bacteria and fungi, but the composition of the cell wall is different from that of the eukaryotic cell.
Hence, the cell is surrounded by the plasma membrane and cell wall in eukaryotes.
