Answer: Animal cell's shape and structure are determined by the cytoskeleton.
What is the cytoskeleton?
The cytoskeleton is present in all animal cells, prokaryotic (bacterial) cells contain a very rudimentary version of it, while plant cells do not have one at all. It consists of several types of large molecules that provide physical support to the cell as well as internal transport along its length for organelles like endoplasmic reticulum (ER), mitochondria, vacuoles, etc. The three main components are microtubules, intermediate filaments and microfilaments which give rise to different structures within the cell. Microtubules are long cylindrical tubes made up of two protein subunits (alpha and beta tubulin) that form a hollow tube. These are the main components of the cytoskeleton, they provide support to the cell while also having transport capacity for organelles like endoplasmic reticulum (ER), mitochondria, vacuoles, etc. Microtubules are dynamic structures which means their state is constantly changing i.e., growing, shrinking or moving around depending on requirements of the cell.
What are the most important benefits trees and fruit-bearing trees?
Answer:
Trees give off oxygen that we need to breathe. Trees reduce the amount of storm water runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding. Many species of wildlife depend on trees for habitat. Trees provide food, protection, and homes for many birds and mammals.

A body was found at 12:22am on April 19. The temperature of the
body when found was 94 degrees. What was the approximate time of death?
please help need asap
Answer:
The correct answer is C (The change of color allowed them to hide better from predators)
Explanation:
Before, the deer mice were easy prey for predators since their color stood out and the predators could find them. Therefore, the change of color allowed them to hide better from predators. You may be tempted to answer a, but if you read carefully it says "The change of color camouflaged them, which helped them HUNT better." Clearly A is wrong since deer mice don't really hunt.

Kinetic energy is described as
Question 1 options:
Decreasing energy
Stored energy
Elastic
Movement
Answer:
elastic
Explanation:
The kinetic energy of a body can be decreased in two cases: When it is stored in the form of potential, for example: elastic or gravitational energy. Or when there are dissipative forces capable of transforming it into other forms of energy, as does the friction force. Which transforms kinetic energy into thermal energy.

Why does litmus paper go blue when ammonium hydroxide touches it
Cetaceans (whales, dolphins, and porpoises) are all Mammals. Whales usually are larger and slower in the water. Porpoises normally do not have a pronounced beak as a dolphin would. Dolphins have a curved dorsal fin. Dolphins and Porpoises are extremely intelligent. They are warm-blooded. All dolphins are whales, but not all whales are dolphins. Different animals live in different areas. Killer whales are adapted to colder areas, and they stay in the colder water. Bottlenose dolphins are best suited for warmer areas such as the Atlantic Ocean, so they will have less body fat or flubber because they live in a warmer climate. The Killer Whale will need more body fat because of the colder temperatures. They have smooth bodies to help them swim. They have tiny hairs, but as they age, the hair disappears. They can stay underwater longer based on their breathing and extract oxygen from water; they make super high pitch noises that Bounce off objects in the water Back towards the Dolphins to help determine the location; this is called Echolocation.

The type of white blood cell that predominated in charlie's CSF is neutrophils.
Cerebrospinal fluid (CSF) is a transparent, colorless plasma ultrafiltrate with little protein and few cells. It is produced in the choroid plexus in the ventricular brain system.
The type of white blood cell that predominated in charlie's CSF is neutrophils. They are granular leucocytes, with active phagocytes. In the cytoplasm, there is the presence of neutral staining granules whose phagocytic activities are integral to subdue the invasion of pathogens.

where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?
Answer:
They use the glucose they have stored from previous photosynthesis reactions.
Explanation:
The dark reaction takes place external to the thylakoids. The energy from ATP and NADPH is used in this process to fix carbon dioxide (CO2).
What is light-independent/dark reactions?Carbon fixation, reduction, and regeneration are the three stages that make up the Calvin cycle, which is another term for the dark reactions that take place during photosynthesis.
The stroma of the chloroplast is the location where the light-independent process, also known as dark reactions or the Calvin-Benson cycle, is carried out. Carbon-based molecules are formed through a chain of chemical events that begin with carbon dioxide. The production of ATP and NADPH during the light-dependent process supplies these processes with the energy they need to proceed.

As the troponin changes shape (due to binding calcium), it moves the ______ molecule to which it is attached, thus exposing the active sites on the G-actin molecules.
As the troponin changes shape (due to binding calcium), it moves the tropomysin molecule to which it is attached.
Once calcium binds to troponin and causes it to change it shape, it removes the tropomysin away from the binding site therefore effectively exposing the myosin binding sites.
This occurs during muscle contraction (movement) in the skeletal muscles.

Compare morphological and bio-
chemical evidence supporting
evolution.
The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
Morphological evidence: Physical structures and traits indicate evolutionary relationships.
Biochemical evidence: Genetic and molecular similarities indicate evolutionary relationships.
Evolution is supported by morphological evidence. Scientists can establish evolutionary links by analysing species' anatomy. Homologous structures, which have a common origin but diverse functions, reflect a shared lineage. Comparative examinations of bone structure, limb arrangement, or body plans can reveal evolutionary links.
Biochemical data emphasises genetic and molecular similarities between organisms. Scientists may compare DNA, protein, and other substances at the molecular level. Common ancestry and evolution explain these commonalities. Comparing genetic sequences can show how closely related species are and when they evolved from a common ancestor.

You are attempting to carry out a transposon mutagenesis experiment using the pRL27 system. The Donor strain you use was giving to you by a lab mate who has been culturing it continuously for several months. When you set up your control plates, you find that the Donor strain grows poorly on Luria DAP Agar. Your transformation efficiency is very poor for this attempt at mutageneis. What likely happened to the Donor strain
The most likely happened to the donor strain is that the transposon is active in the donor resulting in the gradual accumulation of mutations. The accumulation of mutations is promoted by the insertion of the transposon.
A donor strain is a bacterial strain that contains a mobilizable fragment of DNA called plasmid.
These strains (donor strains) exploit the transference properties of a conjugative plasmid to modify a particular recipient strain.
Transposons, also known as jumping genes, are mobile genetic elements that alter the genome of an organism by jumping and thus inserting them into genetic sequences (i.e., into protein-coding sequences).
In this case, the presence of a transposon in the donor strain affected the expression of many genes required for the donor strain in order to grow into Luria DAP Agar.
