What are cells that make up testis (imma need like. At least 2 sentences- 3 sentences pls)
Answer:
Seminiferous,Rete testis, Efferent ducts
Explanation:
Seminiferous tubules are coiled tubes that make up most of each testis. The cells and tissues in the tubules are responsible for spermatogenesis, which is the process of creating sperm.
After sperm is created in the seminiferous tubules, sperm cells travel toward the epididymis through the rete testis. The rete testis helps to mix sperm cells around in the fluid secreted by Sertoli cells. The body reabsorbs this fluid as sperm cells travel from the seminiferous tubules to the epididymis.
The efferent ducts are a series of tubes that join the rete testis to the epididymis. The epididymis stores sperm cells until they’re mature and ready for ejaculation.

In humans the process of digestion begins in the mouth where food is chewed into small pieces by the teeth. The saliva helps by moving pieces these pieces around. These pieces are covered by bland,or spit. The saliva makes the food slippery so it's easier to blank.
Answer:
The saliva makes the food slippery so it's easier to SWALLOW.
Explanation:
Digestion of food begins from the mouth. When the food is chewed, it mixes with the saliva from the salivary gland and this makes the food slippery and easier to swallow. Once it is swallow it moved to pharynx to the oesophagus and down to the stomach where the stomach acid act on it. From there enzymes from the pancreases act on it to break it down and it is moved down to the small intestine where it is absorbed as nutrients and the undigested one move to the large intestine and form faeces.

describe hematopoietic stem cells in your own words
Answer:
Hematopoietic stem cells (HSCs) are the stem cells that give rise to other blood cells. This process is called haematopoiesis. This process occurs in the red bone marrow, in the core of most bones. In embryonic development, the red bone marrow is derived from the layer of the embryo called the mesoderm.
Explanation:
Function: Stem cells that give rise to other blood ...
Location: Bone marrow
System: Hematopoietic system

D
Explanation:
imagine you were collecting vegetation samples in an area to study their distribution over that area. describe how remote sensing images, maps, and GPS and gis could be helpful
Answer:
GPS and GIS help in data collection and guide about geographical distribution.
Explanation:
A GIS is a computer-based, system that aids in data collection, manipulation, and analysis. A GPS is a location tracking system that aids as a map-making tool. Remote sensing is remotely taking pictures of the landscape and physical features of the earth in order to be used for mapping the area. All these act as tools in map making and help to identify the location and map out the distribution of particular phenomenon on the surface of the earth. These tools will act as a guide for collecting vegetation samples.Inside of the cell, energy conversions must take place in order to remove energy from raw materials and turn it into a more useable from.

If an organism is eukaryotic, many celled, can move and cannot make it owns food but must hunt or gather food, which kingdom would it be be placed into?
Answer:
Kingdom Animalia
Explanation:
An organism that is many-celled, can move, and cannot make its own food but must hunt or gather food would be placed in the kingdom Animalia.
Animals are generally heterotrophic, multicellular, and are able to move from one place to another. They ingest their foods and carry out digestion within their bodies and egest out undigested foods.
Animals are different from plants primarily in that they cannot make their own foods through photosynthesis. They are different from fungi in that they cannot carry out extracellular digestion of foods. Also, animals are different from bacteria and protists in that they multicellular rather than being unicellular.

Explain how so many types of cells can be formed even though all the cells have the same DNA.
Because all of your cells in your body started off as single cells. That single cell then divided into multiple other cells. So it breaks down so it can help the entire body equally. In order for a cell to work 1,000 of these proteins need to be created.

What are 3 lab safety practices you will have to follow as you work to cure lactose intolerance
Different lab safety rules should be followed, you should follow the written and verbal instructions, always try to do under direct supervision, never work alone in the laboratory.
What are the lab safety rules ?For lab safety rules we should be aware of hazardous materials, should be well trained before using any lab equipment, maintain the concentration to avoid either spillage of toxic chemicals.
All chemicals should be labelled and stored properly, do not mix up all the chemicals, Emergency plan should be placed, sensible clothes should be wear along with glasses, gloves and footwear.
Loose clothing do not get caught in a flame or chemicals, so it should be used, do not taste or smell chemicals, never pour old stock chemicals , Chemical Hygiene Plan (CHP) should be used which will addresses the specific hazards.
Do not follow un-tested and unauthorized experimental procedure, Never undertake unknown experimentation and clean up all the chemical spill.

Why can't blue whales get cancer?
Answer:
Because it is so big the mutated cell is harmless to them because of teir cell count
Explanation:
Answer:
Even though larger animals like elephants and blue whales have up to 100 billion more cells than humans in their bodies — and therefore many more chances for harmful mutations to develop — they are much more immune to cancer.

.What advantage would using a compound light microscope have over using a dissecting microscope?
The dissecting microscope is configured to allow low magnification of three-dimensional objects- objects larger or thicker than the compound microscope can accommodate. Furthermore, the two separate lenses of the binocular dissecting microscope allow one to see objects in three dimensions, i.e., in stereo

whats the form of Stereoisomerism?
Answer:
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer.

Explain why scientists use shared
characteristics to make cladograms.
Answer:
Scientist use synapomophies, or shared derived characters, to define cladograms. For instance, mammary glands are a shared characteristic of mammals. All mammals and their oldest common ancestor, had or have mammary glands.Thus, if we are looking at an unidentified animal and trying to place it in a cladogram, if it has mammary glands we know it belongs in that branch. Cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
Explanation:
Answer:
Sample Response: Shared characteristics are features or qualities that organisms have in common with each other. They are used to make cladograms because they show the relationships among organisms. They can also show which organisms have a common ancestor.
