Myeloid cells are attracted to and polarized to pro-invasive, immunosuppressive phenotypes by substances released by malignant tumors.
In the glioblastoma (GBM) tumor microenvironment, brain-resident microglia and peripheral macrophages build up and cause immunosuppression, which promotes tumor growth. It is debatable which CSFs are responsible for the increase of myeloid cells in gliomas, however macrophage colony stimulating factors (CSFs) regulate their recruitment during the course of peripheral malignancy.
Five human glioma cell lines and TCGA datasets were used to analyze the expression of CSF2 (encoding granulocyte-macrophage colony stimulating factor). In vitro and in vivo experiments were performed to examine the effects of stable CSF2 knockdown in glioma cells and antibodies that neutralize CSF2 or its receptor, CSF2R.

An organism has 18 chromosomes in its body cells. Its sex cells have 9 chromosomes.
Which statement correctly explains this?
Answers
For an organism that has 18 chromosomes in its body cells and its sex cells have 9 chromosomes, the correct statement is C, Its sex cells are haploid and a result of meiosis.
What are haploids?Haploid cells have half the number of chromosomes as diploid cells. Mitosis is a type of cell division that produces two identical daughter cells. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell.
In the organism described, the body cells are diploid (18 chromosomes) and the sex cells are haploid (9 chromosomes). This is because the sex cells are produced by meiosis, which is a type of cell division that reduces the number of chromosomes by half. This allows the sex cells to combine with each other to form a new diploid cell, which is the beginning of a new organism.

Dopamine receptors are
A. G-protein coupled receptors that only activate adenylyl cyclase
B. G-protein coupled receptors that can either activate or inhibit adenylyl cyclase
C. Ionotropic receptors that are excitatory
D. G-protein coupled receptors that only inhibit adenylyl cyclase
Answers
Dopamine receptors basically G-protein couples receptors which are able to activate or even inhibit adenylyl cyclase.
The correct option is option B.
G-protein-coupled receptors or GPCRs are basically the largest as well as the most diverse group of membrane receptors which are found in eukaryotes. GPCRs happen to interact with the G proteins that are present in the plasma membrane. Whenever an external signaling molecule happens to bind to a GPCR, it leads to a conformational change in GPCR which consequently triggers the interaction between the GPCR and a G protein present nearby.
The common target of these activated G proteins is adenylyl cyclase which is basically a membrane-associated enzyme which when activated catalyzes synthesis of cAMP. Dopamine receptors are also G-protein couples receptors which are able to activate or even inhibit adenylyl cyclase.

The cell membrane performs several important functions in addition to separating the cytoplasm from the outside environment. It controls which molecules enter and leave the cell. The cell membrane is “selectively permeable,” which means it allows certain substances through and not others. One way that substances enter and leave the cell is through diffusion, the movement of particles from higher concentration to lower concentration. For example, if the concentration of salt molecules is higher inside the cell than outside, salt particles will move out of the cell. Diffusion is a type of passive transport, a movement of particles that does not require energy to occur. Facilitated diffusion is a kind of passive transport where proteins in the cell membrane help particles move from high to low concentration.

Answer:
D. When people get together to stop the killing of the hawks, skunks, and weasels.
Explanation:
A and D make answering this problem a bit confusing, but it's the wording that matters.
Answer A, states that Individual ants together make up an ants' nest. In other words, 1 + 1 + 1 + 1 + 1 + 1 + 1 = 7
Great, we understand that a bunch of ants means there's an ants nest in that area, but on the other hand...
Answer D, states that people get together to stop the killing of hawks, skunks, and weasels. Which means, people get together WITH A PURPOSE to stop the killing... And in order to have a purpose to stop the killing, the people must cooperate to make a change.
Otherwise, a crowd of people is just a crowd. No purpose, and no reason for cooperation like the answer choice in A with ants.

.Why do you think some animals migrate while others are able to live in the same place year round?
Answers
Answer:
Climate and Weather: Some animals migrate to avoid extreme weather conditions, such as cold winters or dry seasons. By moving to more favorable climates, they can find suitable temperatures, avoid resource scarcity, or escape harsh environmental conditions.
Answer:
There are several reasons why some animals migrate while others are able to live in the same place year-round. One of the main reasons is related to the availability of resources such as food, water, and shelter. Animals that live in areas with a stable and predictable supply of resources may not need to migrate, while those that live in areas with seasonal changes in resource availability may need to move to find food and water.
Another factor that can influence migration is climate. Animals that are adapted to cold temperatures may migrate to warmer areas during the winter months, while those that are adapted to warmer temperatures may migrate to cooler areas during the summer months.
Genetics and evolution can also play a role in migration patterns. Some species have evolved to migrate as a way to avoid predators or to take advantage of seasonal changes in resource availability. Other species have evolved to stay in one place year-round and have developed adaptations that allow them to survive in their environment without the need to migrate.
Overall, the decision to migrate or stay in one place year-round is influenced by a complex interplay of environmental, genetic, and evolutionary factors.

Osteoporosis is more prevalent among women than men because women generally
have more bones in their bodies than men have.
take in more calcium than men take in.
have lower bone mass than men have.
exercise more than men do
Answers
Answer:
Have lower bone mass than men have
Explanation:
Osteoporosis is a bone thinning disease that is more prevalent among women than men and typically occurs after 50. The reason women are more likely to get the disease than men is because after 50 many women have gone through or are going through menopause. Menopause causes the ovaries to produce less estrogen which is what had previously been promoting bone density.
The other answers are incorrect because...
A: have more bones in their bodies than men have: for the most part everyone has the same amount of bone in there body (although there are diseases that cause a persons bones to fuse together making them have fewer bones than the average person)
B: take in more calcium then men take in: more calcium would actually cause someone to be less likely to get osteoporosis because it strengthens the bones.
C: exercise more than men do: Osteoporosis is more common in malnourished women and women who do not get regular physical activity to strengthens there bones. So getting more exercise would actually lessen the chance of getting osteoporosis.

C. Fission
D. Tidal
Answers
Atomic fission is the process through which energy is produced. The right answer is C.
Atomic splitting produces a particular form of energy known as fission. It is a nuclear process in which a huge quantity of energy is released along with the splitting of an atom's nucleus into two or more smaller nuclei.
In fission, neutrons are used to hit heavy atomic nuclei, such as uranium-235 or plutonium-239, creating an unstable nucleus.
Then, this nucleus splits into two or more smaller nuclei, releasing more neutrons and a substantial amount of energy in the process.
Thus, the correct option is C.

write a short paragraph (5 sentences or more) about photosynthesis using (all) the terms plant, chloroplast, chlorophyll, pigment, sugar, oxygen, and sunlight.
Answers
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water, "light", and sunthesis, "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP).
The chloroplast is the site of photosynthesis. Part of the photosynthesis reactions occurs in an internal membrane within the organelle.
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, Sunlight energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds{sugars)
Chlorophyll is a green coloured pigment present in the leaves of plants. Chlorophyll absorbs the solar energy from the sunlight during the process of photosynthesis.
What are the 3 stages of photosynthesis?The three steps that occur during the process of photosynthesis are:
(i) Absorption of light energy by chlorophyll.
(ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
(iii) Reduction of carbon dioxide to carbohydrates.
Thus, photosynthesis is an energy driving process in plants.
