Answer:
C. Mitosis, Gene expression, differentiation
Explanation:
Stem cells are referred to as undifferentiated cells which has the ability to develop into new specialized cells via cellular differentiation. The stem cell initially undergoes MITOTIC division to form new stem cells.
This stem cells then undergo GENE EXPRESSION by turning off some genes and turning on some in order to specialize the cell type. After this, the cell becomes DIFFERENTIATED i.e becomes another type of cell
Place the phases of a stem cell into the correct order.
The correct order would be mitosis, gene expression and then differentiation.
Stem cells can be defined as undifferentiated cells that possesses the ability to develop into many other different cells of the body. Before a stem cell becomes differentiated, the stem cell undergoes growth, mitosis and then information from the gene (DNA) in the cell will be needed to determine the type of cell it will become and be expressed before differentiating and becoming specialized to give rise to a particular type of cell.

Answer:
Explanation:
Photosynthesis Takes Place in Chloroplasts. ... The inner membrane surrounds a stroma, which is the site of the carbon chemistry of photosynthesis
sorry if im wrong
Photosynthesis occurs in chloroplast thylakoid membranes. Electron transport chains produce ATP and NADPH. Therefore, option (A) is correct.
What are chloroplasts?Chloroplasts are plastids that are made up of an outer membrane, an inner membrane, grana, and the stroma. These four components make up the chloroplast. The inner membrane encloses a region that is filled with fluid and is known as the stroma. This region includes enzymes that are responsible for light-independent processes that occur during photosynthesis. When this inner membrane is folded inward, it creates linked stacks of disk-like sacs known as thylakoids. These thylakoids are frequently grouped in stacks that are called grana.
The chemical reaction known as photosynthesis, which converts sugar and oxygen from carbon dioxide and sunlight, takes place in chloroplasts, which are found in plant cells.

A snake catches and eats a small field mouse. Later that day, a hawk catches the snake and eats it. Which three terms describe the snake? consumer, predator, prey parasite, predator, producer predator, producer, consumer prey, parasite, producer
Answer:
Consumer, predator, and prey.
Explanation:
The snake is a consumer and a predator because it eats or consumes another organism (the mouse), but it is also prey because it is consumed or preyed upon by another predator (the hawk).
The three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.
What is Predator?A predator may be characterized as a type of animal that significantly obtains food by killing and consuming other organisms in the form of food and taking energy for the metabolic processes. These animals hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey.
According to the context of this question, when a snake eats a mouse, it is called a consumer and predator because it actually drives energy from the mouse in order to facilitate its metabolic processes. When a hawk when catches a snake and eats it, it is often known as prey, and the hawk is known as a predator in this case.
Therefore, the three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.

Which statement best describes the effect on water transport across the cell membrane if the aquaporin in the figure ceases to function?
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).

Besides poaching, what other major factor is causing a decline in elephant populations?
Answer:Habitat Loss and conflict with communities
Explanation: Habitat loss and conflict with communities
Most elephant habitat still extends outside protected areas, and the rapid growth of human populations and the extension of agriculture into rangelands and forests formerly considered unsuitable for farming mean that elephant habitat is continuing to be lost.
Increasing conflict with people
As human populations expand, more land is being converted to agriculture. So elephant habitat is shrinking and becoming more fragmented, and people and elephants are increasingly coming into contact - and conflict - with each other.
Elephants sometimes raid farmers’ fields and damage their crops – affecting the farmers’ livelihoods – and may even kill people. Elephants are sometimes killed in retaliation.
With human populations continuing to grow across their range, habitat loss and degradation - and conflict with communities - will remain major threats to elephants' survival.
Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.
What are the reason behind the decline of the population of elephants?The reason behind the decline of the population of elephants are poaching, besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.The logistics growth curve has been defined as the population per capita growth rate is decreases and get smaller and the size of population increases maximum applied by resources which are limited in the environment which is known as the K that has been carrying capacity.
The logistics population growth has been represented by the logistic growth curve on a line graph and the shape of the curve has S - shaped that represents the slow increase, and rapid growth in the population and after that there has been reduction in the growth.
The best example of the logistics growth has observed in the wild population that includes the sheep as well as harbor seals. In both of the cases the number of the population has been increases and carrying capacity for small period of time.
Therefore, Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.

Match each tool with its influence on science
Answer:
xray - allows scientists to see dense structures
Microscope - view things that cannot be seen with the naked eye
Telescope - stars, planets and black holes
Ultrasound - see inside the body in real time
Explanation:
Xrays shows highlights dense structures within the body (bones). But is not in real time, usually there images that are captured and reviews later.
Microscope - the clue is in the name, think micro= tiny! Therefore cant be seen by the naked eye. The "scope" part of the word means to look at or observe. So put them together and you get to look at or observe tiny things.
Telescope - the first part of this word "tele", means something far away or at distance. Which gives a clue at what it does, add on the "scope" meaning of to look at or observe and you get; to look at or observe something that is far away.
Ultrasound - this is what is used to monitor the health of babies when they're still developing. It can be seen in real time.
X-rays enable researchers to observe dense formations. View objects using a microscope that is invisible to the eye. Telescope: black holes, planets, and stars see into the body in real-time using ultrasound.
What is the tool microscope's influence on science?X-rays depict the body's dense internal architecture (bones). But it's not in real-time, typically, pictures are taken and then looked at afterward.
The name of the instrument, "microscope," gives it away—think small! as a result, not visible to the eye. The word "telescope" refers to anything far out or remote in its first half.
When a baby is still developing, their health is monitored using ultrasound technology.

Complete the Concept Map to compare the locations and remodeling functions of osteoblasts and osteoclasts, and explain how hormones and physical stress regulate bone remodeling.
Answer:
The correct answer is attached as an image.
Explanation:
Bone remodeling occurs by the remodeling units osteoblast which is bone deposition and osteoclast which is Bone resorption.
Bone deposition is the process that involves the deposition of minerals in bone tissues which takes place due to the process of osteoblast mainly. the bone deposition is possible in three ways when
- there is an increase in blood calcium.
- there is an increase in mechanical stress.
- decrease in parathyroid hormone
Osteoclast cause the degrade of bone tissue by releasing calcium ion from bone tissue which required opposite conditions than osteoblast that are -
- there is a decrease in blood calcium.
- there is a decrease in mechanical stress.
- increase in parathyroid hormone
A decrease in blood Ca++ concentration causes the parathyroid gland to release PTH, PTH results in osteoclasts to degrade bone tissue which releases Ca++ into the blood. A high level of Ca++, calcitonin results in calcium deposition into the bone.
