Answer:
Both
Explanation:
Answer:
Cell membranes are in both Plant and Animals cells.
Explanation:
Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane, they both give the plant structure and support. Animal cells simply have a cell membrane, but no cell wall.
Deforestation leads to environmental imbalance. Give reason.
Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.
What is the Law of Universal Gravitation and how did it differ from the understanding of the motion before Newton theorized it?
How do you think Newton’s discoveries help to pave the way for his Three Laws of
Motion?
Answer:
While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits. At the age of 27, Kepler became the assistant of a wealthy astronomer, Tycho Brahe, who asked him to define the orbit of Mars. Brahe had collected a lifetime of astronomical observations, which, on his death, passed into Kepler’s hands. (Brahe, who had his own Earth-centered model of the Universe, withheld the bulk of his observations from Kepler at least in part because he did not want Kepler to use them to prove Copernican theory correct.) Using these observations, Kepler found that the orbits of the planets followed three laws.
When biologists talk about a population of organisms, they are referring to
A) all the organisms in a particular area
B) all the organisms all over the world
C) all the organisms of one species in a particular area
D) all the organisms of one species all over the world
Answer:
C because it couldn't be D
When biologists talk about a population of organisms, they are referring to all the organisms of one species in a particular area. Therefore, option (C) is correct.
A population is a group of individuals of the same species living in a particular geographical area and capable of interbreeding. This means that they share a gene pool and can produce fertile offspring. The size and characteristics of a population can be influenced by various factors, such as environmental conditions, competition for resources, predation, and disease.
Studying populations is essential for understanding how ecosystems function and how they may respond to changes in the environment or human activities, such as habitat destruction or climate change.

What is the name of a specific type of model that shows how animals diverge during evolution?(1 point)
taxonomy
hierarchy
diagram
cladogram
Answer:
Cladogram.
Explanation:
A cladogram is a diagram used in cladistics to show relations among organisms. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. In biology, taxonomy is the scientific study of naming, defining and classifying groups of biological organisms based on shared characteristics. Taxonomy would not be based on genetic diversion during evolution, it only describes similar characteristics amongst animals.
I also chose taxonomy on the test and it was wrong. The right answer said cladogram.
A specific type of model that shows how animals diverge during evolution is Cladogram. So, the correct option is D.
What do you mean by Evolution?Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms.
A cladogram is a diagram that shows the evolutionary relationships of several clades. A clade is a group of organisms, which contains both an ancestral species and its descendants. The common ancestor appears at the root of the cladogram.
Therefore, A specific type of model that shows how animals diverge during evolution is Cladogram.

Just as slow-moving water loses sediment, fast-moving water can pick up new sediment to carry. Which part of the river
bend will experience the greatest amount of new erosion? How will this erosion affect the shape of the river?
Answer:
The part of a riverbend that will experience the most erosion is the inside corner, this is because the water will be hitting it on two sides, the erosion will likely curve the inside corner more.
The water flowing at the maximum velocity and with the greatest ability to erode is on the outside of the curve, rivers that meander erode in both directions.
What factors affect the river?Cut bank erosion occurs when the edge of a stream channel bends, and it increases the loop of the meander, water that moves more quickly has greater kinetic energy.
It can therefore transport bigger particles, more articles may also be carried by it, and bigger and larger particles can be carried by a stream as it moves more quickly. The capacity of a stream increases with the size of the particles it can transport.
Therefore, a stream will have a quicker velocity if it has a steep slope or gradient, which implies it may transport heavier items in suspension.

what is dna ? and what is the purpose of dna
Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
Explanation:
-Eijiro <3
First, it has to be able to make copies of itself because you're making new cells all the time and your cells have to have a copy of your DNA so it has to do what we call replication.
It also has to store all the information about your body as far as your body chemistry, your proteins, your amino acids, and all the things that make you.
One more very important job of DNA is that it's responsible for this process called protein synthesis which is the process in which cells make proteins. So every piece of your body from your fingernails, your eyeballs, and many other things are made up of proteins, proteins are the building blocks of you and the DNA determines the shape and function of your proteins. You think of DNA as a set of instructions on how to make the proteins that make you.

In dense forests, obtaining sunlight for plants can be tricky. Growing on the ground is not always effective for plants because there is not much sunlight hitting the ground. Orchids are epiphytes, or plants that grow on other plants. They grow on branches of trees high up in the canopy. They get more sunlight and have more access to pollinators up in the high branches. Orchids lay their roots on the bark of a tree and obtain nutrients and water from their surrounding environment.
In a short answer, identify and describe the type of symbiotic relationship between orchids and the forest trees, and explain the effect of this interaction on each species involved.
Explanation:
The symbiotic relationship between orchids and trees is called commensalism, which means the orchid and tree host depend on eachother to survive.. The orchid provides the tree with sunlight, (nutrients created by sun- exposure).
the tree provides a solid base for the orchid to climb up the tree, they are dependent on eachother for survival...
The type of symbiotic relationship between orchids and forest trees is commensalism.
What is commensalism?Commensalism is a relationship in which one species benefits while the other is neither helped nor harmed. In this case, orchids benefit from the elevated position and access to sunlight provided by the trees, while the trees are neither helped nor harmed.
The effect of this interaction on orchids is that they are able to thrive in a challenging environment where they would not otherwise survive. The effect on forest trees is neutral, as the orchids do not harm or compete with them for resources. However, the presence of orchids on the tree bark may attract pollinators or other organisms, which could potentially benefit the trees indirectly.

A
Interphase
B
Cytokinesis
C
Prophase
D
Anaphase
Answer:
I think interphase because fna synthesis happens within the s-phase of the cell cylce and 5he s phase is suring interphase and not mitosis
The phase of the cell cycle which is most affected by Cytarabine is the Interphase. Thus, the correct option is A.
What is the cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The entire cell cycle can be divided into two phases.
The InterphaseThe M-phase (division phase).As per the question, the drug Cytarabine inhibits the synthesis of DNA, it definitely inhibits the interphase of the cell cycle. This is because the synthesis of DNA occurs in the S-phase of the cell cycle which is a substage of the interphase.

What scientist used radioactive bacteriophages to prove DNA is the
hereditary material passed from one generation to the next?
Answer:
Alfred Hershey and Martha Chase
Explanation:
In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.
