Which type of reproduction involves the passing of characteristics to offspring? A. only sexual
B. only asexual
C. both sexual and asexual

Answer:
C. both sexual and asexual
Explanation:
In both cases, the parent(s) of the offspring pass down characteristics. Asexual reproduction makes a carbon copy of the parent so they would obviously have the parent's characteristics. Sexual reproduction passes down characteristics of both parents to the offspring.

why is the moon white
Moonlight is no longer thought of as the cause. In the 16th century, moonmilk, a soft white limestone precipitate found in caves, was thought to be caused by the rays of the Moon.
Answer:
The moon is not actually white, it's grey.
Explanation:
What I learned is that what makes it white is the reflection of the sun and the sun makes it glow, that's why it looks white.
And if you focus on the moon when it's not full you'll see the other part of it showing but it looks grey not white, because as I told you it's the suns reflection.

Gradually you notice that the large chamber walls seem to be closing in. You hear a thundering boom, and the whole chamber vibrates as the valve slams shut above you. The cords, now rigid and strained, form a cage about you, and you feel extreme pressure. Obviously, the lower chambers of the heart are in a full-fledged _____5______. Then, high above on the right, the "roof" opens, and you are forced through another valve which has led you into a very large artery. As you are swept along in a huge artery(the largest artery in the body), the____6_____, you pass several branch-off points, but continue to careen (fall) along, straight down at a dizzying speed until you approach the artery feeding the small intestine. After entering this artery and passing through successively smaller and smaller subdivisions of it, you finally reach the smallest blood vessels the_____7_______. You watch with fascination as nutrient molecules move into the blood through the single layer of ______8______(look at power point notes) cells forming the capillary (blood vessel) wall. As you move forward and you begin to move superiorly (up) once again, you enter the huge_______9______, which returns blood from the lower part of the body to the_______10_______of the heart. From here, you move consecutively through the right chambers of the heart into the_______11______artery, which carries you to the _____12_____to get ______13______and then back to the left side of the heart again where you started

Explanation:
Histones are 8 subunit proteins that cells use to pack DNA into the manageable condensed chromosomes you are used to seeing during mitosis or meiosis (functioning somewhat like hair rollers for DNA). Under normal circumstances, DNA binds TIGHTLY to histones. Given what you know about DNA structure, predict which amino acids are concentrated on the outer surface of histones that interacts with the backbone of DNA?
Answer: Arginine and Lysine
Explanation:
Histones are protein that packs DNA into nucleosomes. It compose of Arginine and Lysine amino acids.
Lysine and Arginine are basic amino acids that aids the solubility of Histone in water and also aids the interaction of DNA and Histones.
The amino acids that are concentrated on the outer surface of histones and interact with the backbone of DNA are ARGININE and LYSINE, which are positively charged (i.e., they are basic amino acids).
In eukaryotic cells, Deoxyribonucleic acid (DNA) is tightly packed by its interaction with histone proteins. A nucleosome is the functional and structural unit of eukaryotic chromatin, which is composed of an octamer of histone proteins (two subunits of H2A, H2B, H3 and H4 histone proteins) and approximately 147 base pairs of DNA.The phosphate backbone of the DNA double helix is negatively charged because phosphate bonds between phosphorous atoms and oxygen atoms have a negative charge.In consequence, the tight wrapping of DNA around histones is due to the attraction between the phosphate backbone of the DNA molecule and positively charged amino acids of histones.In conclusion, the amino acids that are concentrated on the outer surface of histones and interact with the backbone of DNA are ARGININE and LYSINE, which are positively charged (i.e., they are basic amino acids).

Conservationistis strive to preserve or improve biodiversity in ecosystems, which includes monitoring populations of organisms to detect changes. Name two challenges that scientists may encounter when they’re monitoring populations of organisms in the wild.
Answer:
Conservationists are responsible to preserve or improve the biodiversity in ecosystem. Many wildlife sanctuaries are made to protect the biodiversity. There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.
Two main challenges conservationists will face while monitoring population of organisms in wild are:
weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.Hence, conservationists face the above challenges while dealing with wild.
Answer:
One challenge is cost. To effectively monitor populations in the wild, scientists need special equipment such as cameras, computers, and GPS monitoring equipment. Another challenge is accuracy. It’s impossible to count every single organism in an ecosystem, so scientists often work with estimates.

how the structure of synapse ensures that impulses travel in one direction
Synapse
It carries information through electrical impulses to the cell body.
It is the gap between neurons.
It ensures that information travels in one direction only.
Explanation:
A synapse is the gap or the junction where two or more neurons or nerve cells meet together.
Also called the synaptic cleft, the synaptic gap receives the electrical signals and passes them through one nerve cell to another
The axon nerve endings release neurotransmitters which ensure that the path of transmission of impulses is only unidirectional – only from presynaptic to postsynaptic path.
The synaptic gap between a nerve cell and an effector muscle cell is referred as the neuromuscular junction.
"After scanning the green labeled areas and the red labeled areas, when we combine the two images, the spots that show up as yellow correspond to "
Answer:
... areas labeled both red and green.
Explanation:
The spots that show up as yellow correspond to areas labeled both red and green.
__
The effect of combining images will depend on the method used to create the combination. There are many possibilities when combining color images.
When mixing red and green light, yellow light is produced. When mixing red and green pigment, brown pigment is produced. When mixing digital representations of red and green, the effect depends on the individual representations, the method of mixing, and the interpretation of the mixed result.
__
Given the way the question is worded, we assume that yellow is produced by a combination of red and green appearing in the same area of the images. That is, ...
The spots that show up as yellow correspond to areas labeled both red and green.
