The plant cell below has some damaged organelles. What would MOST LIKELY result from this damage to the cell?
Answer:
If cell wall of a plant is damaged, the cell will be collapsed. The cell wall separates the cytoplasm from external environment and protects cell organelles. without cell wall they will be damaged. Cell also acts as permeable membrane for solvents and ions which cannot happen when cell wall is damaged.
Explanation:
Which of these cell parts contains instructions for the passage of traits from one generation to the next? (ignore the answer I put)

PLZ thank and five star
and a brainliest would be nice:-)
Answer: D. the amount of space something takes up
============================================================
Explanation:
For example, if you have a 2 inch by 3 inch by 5 inch rectangular block, then the volume it takes up is 2*3*5 = 30 cubic inches. We can fit 30 smaller unit cubes in this 2 by 3 by 5 block.
Another example of volume would be saying that a container can hold 5 gallons, which is the amount of liquid inside the container when it's completely full.
----------
Extra info:
Choice A is false because a substance that does not have a definite shape would be a liquid. Liquids can flow and form to fit any volume. This also applies to a gas as well.Choice B is false because this refers to a solid. A block of ice has a definite shape which is in a block or cube form. Melting that ice will turn it into a liquid which then doesn't have a set shape.Choice C is false as this likely is talking about temperature. Temperature is the measure of how fast a particle is moving. The faster the particle, the more energy and higher temperature it has. On a cold day, the air particles aren't moving as fast compared to a much warmer day when they speed up more.The text is divided into sections with subheadings.

A few years ago the population of male blue moon butterflies on the island of Samoa declined. One hypothesis for the decline of the male butterflies is that a parasite infected the cells of female butterflies. The parasite was passed to offspring through the females’ eggs and killed the male butterfly embryos. At one point during the decline, nearly all the butterflies in the population were females, but after five years the number of males in the population increased significantly.
Which explanation most likely accounts for the increase in the number of male butterflies in the five years after the initial parasite problem?
Male butterflies in the population that survived were able to prey on the parasites living in the females’ egg cells.
Female butterflies in the population that survived had a genetic adaptation that allowed them to transform into male butterflies.
Male butterflies in the population that survived had a gene that made them resistant to the parasite, and they passed the gene on to their offspring.
Female butterflies in the population that survived were able to protect the male eggs from the parasite and provide extra care for the male offspring.
One hypothesis which can explain the increase in the number of male butterflies is that the male butterflies in the population survived had a gene that made them resistant to the parasite, and passed the gene on to their offspring. Thus, the correct option is C.
What is Population growth?Population growth is the change in the number of individuals or species in a population. A population is the sum total of all the living organisms which are living in a particular environment.
According to the situation, the number of males in the population has increased significantly. This increase in the number or the population growth of males can be explained as the male butterflies in the population that survived earlier had a gene which made them resistant to the parasite, and they passed on the gene to their offspring which lead to the increase in the number of males in the population.
Therefore, the correct option is C.

Research and describe the biotic and abiotic factors that work together to create your animal’s habitat. You must research and describe at least 5 total factors, maybe 2 from biotic and 3 from abiotic. You mix how you choose as long as you have a mix of biotic and abiotic totaling 5! Look at the last 2 bullet points below for help.
Describe the impact of your vertebrate (animal) on humans.
Describe humans’ impact on your vertebrate.
You must use at least 2 different resources to find your information.
Biotic Factors to explore--- predators, food preferences and supply, population density (how many of that population in that habitat), other species with which your vertebrate interacts in its habitat (think about your symbiotic relationships-mutualism, commensalism, parasitism), disease
Abiotic Factors to explore---temperature range, precipitation, water, topography (what are the land features-hilly, mountainous, flat, combination), wind, shelter, nesting site and place to raise young, escape routes from predators
Answer: Relevance
The scope of abiotic and biotic factors spans across the entire biosphere, or global sum
of all ecosystems. Such factors can have relevance for an individual within a species,
its community or an entire population. For instance, disease is a biotic factor affecting
the survival of an individual and its community. Temperature is an abiotic factor with the
same relevance.
Some factors have greater relevance for an entire ecosystem. Abiotic and biotic factors
combine to create a system or, more precisely, an ecosystem, meaning a community of
living and nonliving things considered as a unit. In this case, abiotic factors span as far
as the pH of the soil and water, types of nutrients available and even the length of the
day. Biotic factors such as the presence of autotrophs or self-nourishing organisms
such as plants, and the diversity of consumers also affect an entire ecosystem.
Influencing Factors
Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting
factors restrict the growth of populations. They help determine the types and numbers
of organisms able to exist within an environment.
Biotic factors are living things that directly or indirectly affect organisms within an
environment. This includes the organisms themselves, other organisms, interactions
between living organisms and even their waste. Other biotic factors include parasitism,
disease, and predation (the act of one anim

I need help with this!! Questions are in the picture!! Feel free to only do 1 or 2 questions!! Doing all is really really appreciated tho!!
Answer:
9. D (100%)
10. C (Round and Wrinkled)
11. C (75%)
12. B (25%)
Explanation:
9. 100% will be brown, because brown (B) is dominant. That means that if all squares have Bb or BB once you fil out the punnett square, then the offspring would have to show the dominant trait. In this example, all possibilities for the organism were Bb, so brown.
10. Rr and rr are being crossed in this example. Heterozygous is Rr, Wrinkled is rr and Round is RR or Rr. The answer id Round and Wrinkled because one parent is Rr (round) and the other is rr (wrinkled).
11. Yellow seeds are dominant, so any box that has at least one Y will be dominant. 3 of the 4 boxed have a Y, therefore there is a 75% chance the offspring will be yellow.
12. Long hair is not the dominant trait, it is recessive. This means any box WITHOUT a capital S will be recessive. There will be one box, the lower left box. It will be ss. Since one out of four are ss, that means there is a 25% chance the guinea pig will have long hair.

First Inaugural Address of Andrew Jackson, selected quotes
WEDNESDAY, MARCH 4, 1829
"Fellow-Citizens:
... In administering the laws of Congress I shall keep steadily in view the limitations as well as the extent of the Executive power trusting thereby to discharge the functions of my office without transcending its authority. ...
In such measures as I may be called on to pursue in regard to the rights of the separate States I hope to be animated by a proper respect for those sovereign members of our Union, ...
This I shall aim at the more anxiously both because it will facilitate the extinguishment of the national debt, the unnecessary duration of which is incompatible with real independence, ...
that the spirit of equity, caution and compromise in which the Constitution was formed requires that the great interests of agriculture, commerce, and manufactures should be equally favored ...
As long as our Government is administered for the good of the people, and is regulated by their will; as long as it secures to us the rights of person and of property, liberty of conscience and of the press, it will be worth defending ... "

when hormone levels in the body are all equal
during a negative feedback loop
during a positive feedback loop
when the hypothalamus is signaling the pituitary gland
The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.

Birds share many similarities with a certain group of dinosaurs that includes the Tyrannosaurus Rex and the Velociraptor. Like birds, these dinosaurs had hollow bones and scales. Fossil evidence shows that many had feathers and some could fly. Evidence also suggests these dinosaurs were warm-blooded.
Given the similarities, identify one characteristic that could be used to differentiate birds from dinosaurs.
Answer:
Size
Explanation:
Dinosaurs, based on recent studies show that they were larger animals and its not possible now for a bird to be the same height or weight as a dinosaur back then
Birds and dinosaurs have found to share many similarities such as presence of feathers, laying eggs, warm blood however the size difference is the main differentiating characteristic between the two.
What are evolutionary links?Different species are related to each other and are gradually undergoing change over time. Evolution in a population affects the physical characteristics of an organism. The ancestors and links between two species can be found with the help of evolutionary links.
The features or evolutionary links between birds and reptiles i.e., dinosaurs are walking on two legs, having feathers, laying eggs, warm bloodedness. All these traits are inherited features from dinosaurs. The difference between dinosaurs and birds is in the size of their body and absence of scales on the birds body.

California’s San Andres fault is known for its earthquakes. The Pacific plate and North American plate are sliding against each other at this example of a strike-slip fault boundary.
What is Strike-slip fault boundary?Strike-slip faults are the vertical or nearly vertical fractures that occur where the blocks have mostly moved horizontally over each other. If the block opposite an observer, then the fault moves to the right, the slip style is termed right-lateral in this case and if the block moves to the left, the motion is termed left-lateral motion of the block.
The cause of the strike-slip fault earthquakes is due to the movement of the two plates which are against one another and the release of built up strain from these plates. As the larger plates are pushed or pulled in different directions they build up the strain against adjacent plates until it finally fails. The Pacific plate and North American plate sliding against each other is an example of strike-slip fault.
