Identify the following particles as being charged or uncharged/neutral. If charged, indicate whether they are charged positively or negatively. (n = neutron, p = proton, e = electron)
*particle C
proton +20
electron -18
urgent ^^
Answer:
Particle A is negatively charged.
Particle B is neutral.
Particle C is positively charged.
Explanation:
Particle A is negatively charged because the number of electrons is more than number of protons so the particle gain negative charge. Particle A is neutral due to same number of proton and electron which cancels the effect of one another and become neutral whereas the Particle B is positively charged due presence of more number of protons as compared to number of electrons so the particle gain positive charge.
if a plant has three leaves in a cluster, you should avoid it because? it isn’t edible. it attracts insects. it causes painful, itchy rashes. it produces poison berries.
Answer:
Your answer would be: it causes painful, itchy rashes
Explanation:
Poison ivy, a common plant, has leaves that always appear in bunches of three leaflets. Poison ivy has an oily resin called urushiol that is in its stem, leaves and roots. When touched, it causes an allergic reaction that can cause redness, itching, swelling, blisters, and other nasty symptoms.

What kind of cells are formed during Meiosis?
nerve cells
Option 4
body/somatic cells
sex cells
animal cells
Answer:
Sex cells.
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

which of the following requires ATP
A. facilitated diffusion
B.Simple diffusion
C.Active transport
D.None of the above
Answer:
Active transport
Explanation:
The process is considered "active" due to the use of ATP and actively requiring energy to transport molecules. Simple diffusion simply occurs through the membrane and facilitated diffusion uses transport proteins, but not ATP, hence why both are considered forms of "passive" transport.
11. Why is the mantle of the Earth described as a semi-solid?

C) The mantle is liquid during warmer months and solid during colder months.
D) The mantle is so hot that it allows the rocky material to flow gradually.
Answer:
D) The mantle is so hot that it allows the rocky material to flow gradually.
Explanation:
Accelerate 2022
The mantle is so hot that it allows the rocky material to flow gradually. The correct option is D.
What are the layers of Earth?The crust, mantle, outer core, and inner core are the four principal parts that make up the earth's structure.
Each layer has a distinct chemical make-up, physical state, and potential to affect life on the surface of the Earth.
The crust, mantle, and core are the three layers that make up the earth. This stratum of the earth lies on the surface and is composed primarily of granite and basalt solid rock.
Oceanic and continental crust are the two different types. The majority of the oceanic crust is made of basalt and is denser and thinner.
The Earth's mantle is regarded as being semi-solid. Because the mantle is so heated, the rocky material can flow gently.
Thus, the correct option is D.

Explain how cellular processes must be altered in stomach cancer cells compared with normal stomach cells to result in the different levels of SIRT3 expression observed.?
Answer:
SIRT3 is a tumor suppressor gene that controls essential cellular processes including apoptosis, cell proliferation, survival and anoikis resistance
Explanation:
The Sirtuin-3 (SIRT3) gene encodes for a histone deacetylase enzyme involved in the epigenetic regulation of many essential genes, thereby controlling their expression levels. SIRT3 has a proapoptotic function that initiates apoptotic events in cancer cells. Moreover, SIRT3 also modulates cell proliferation and survival in both normal and tumorigenic cells by controlling the expression of genes that maintain Reactive oxygen species (ROS) at non-toxic levels. Finally, SIRT3 also mediates anoikis resistance (i.e., the resistance to detachment-induced cell death), thereby inhibiting tumorigenesis in cancer cells. It is for all these reasons that it has been proposed that SIRT3 represents a potential drug target for cancer therapy.

(2 points)
a
Observe at what stage the bugs are able to reproduce. If they reproduce quickly, they go through incomplete metamorphosis.
b
Observe how long it takes the insect to develop. The insect that goes through incomplete metamorphosis will develop quicker.
c
Observe how the insect changes as it develops. If the insect develops a cocoon, it is likely going through complete metamorphosis.
d
Observe what the insect eats over time. If it eats other bugs, it likely goes through complete metamorphosis please answer all I give brainlest
Answer:
1. c . The life cycles of insects and animals all start from a fertilized egg.
2. d . A bee goes through a pupa stage, while the grasshopper goes through a nymph stage.
3. b . I and II
Explanation:
The egg fertilization is very important for the emergence of almost all organisms. If the egg is fertilized then it will change into an organism otherwise no organism is produced from that unfertilized egg. The bees has four distinct life stages i.e. the egg, larva, pupa and adult whereas grasshopper has three stages i.e. egg, nymph, and adult. A moth and an eagle both start their life cycle as a fertilized egg and moth and an eagle both hatch from an egg which is laid by the mother outside of their body..

If a new variety of a tree was produced by botanists through selective breeding that had a growth rate 3 times that of the trees in the scenario, how would that have affected the outcome of the simulation?
Answer:
Greatly affected the outcome simulation.
Explanation:
This fast growth have greatly affected the outcome of the simulation because the tree takes less time to mature and completed its growth stages faster as compared to the old tree. The selective breeding included certain hormones that increases the rate of growth in the tree which leads to change and affected the outcome of the simulation.

how are carbohydrates digested
Explanation:
dbbdhdhdhxhxbxbbxbxbxbcbxbcbcchcbbcbcbcbcbcbcbccbcbcbbcbcbc
Answer:
The mechanical and chemical digestion of carbohydrates begins in the mouth. Chewing, also known as mastication, crumbles the carbohydrate foods into smaller and smaller pieces. The salivary glands in the oral cavity secrete saliva that coats the food particles. Saliva contains the enzyme, salivary amylase. This enzyme breaks the bonds between the monomeric sugar units of disaccharides, oligosaccharides, and starches. The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose. The increased concentration of maltose in the mouth that results from the mechanical and chemical breakdown of starches in whole grains is what enhances their sweetness. Only about five percent of starches are broken down in the mouth. (This is a good thing as more glucose in the mouth would lead to more tooth decay.) When carbohydrates reach the stomach no further chemical breakdown occurs because the amylase enzyme does not function in the acidic conditions of the stomach. But the mechanical breakdown is ongoing—the strong peristaltic contractions of the stomach mix the carbohydrates into the more uniform mixture of chyme.
