Answer:
Plants are amazing organisms! In a process called photosynthesis, they take sunlight energy from the sun,carbon dioxide gas from the air, and water from the ground and make glucose (food energy)! They also make oxygen during this process. Plants can either immediately use the glucose they make to power their cells or sto… use.

If mitosis but not cytokinesis occurred in onion root tip cells, what would you expect to see on a slide of these root cells?
Answers
Answer: Well, cytokines happens after mitosis so you wouldn't see the daughter cells dividing yet.
Explanation: Onion root-tip cells divide once every 24 hours, or roughly two hours after sunrise, and go through a cell cycle that lasts for about 24 hours. Therefore, in order to harvest the greatest amount of proliferating cells, water-grown roots should only be removed at that time.

What could result if tryptophan cannot cross into the cell?
A decrease in tryptophan levels in the blood
A build-up of tryptophan levels in the blood
Answers
If tryptophan cannot cross into the cell, there will be a build-up of tryptophan levels in the blood (option B).
How do substances move into cells?Tryptophan is an essential amino acid having an indole side chain. It is present in many foods, especially chocolate, oats, bananas and milk.
Tryptophan is essential for normal growth and development and is the precursor of serotonin and niacin. This amino acid is carried by the blood and is absorbed by living cells for use.
However, in a case whereby tryptophan cannot cross into the cells, it becomes built-up in the blood and increase in concentration.

WILL MARK BRAINLIEST!!!!
Answers
Note that the experiment you are performing is known as "Solar water distillation" experiment.
The water in the cup is probably unclean because the dirt and water combination in the bowl filtered through the plastic wrap and into the cup via evaporation and condensation.
The plastic wrap represents the Earth's atmosphere, while the water in the cup represents purified water collected, or "distilled," by evaporation and condensation.
The water in the bowl would have evaporated and condensed on the inside of the plastic wrap, running down and into the cup. Evaporation and condensation are the two components of the water cycle at an action in this research.
What is the purpose of the above experiment?The goal of the preceding experiment is to illustrate and comprehend the process of solar water distillation, which is a method of purifying water using the energy of the sun.
The experiment replicates the evaporation and condensation processes, in which the sun's heat causes the water in the bowl to evaporate and then condenses on the plastic wrap, pouring down into the cup.
The dirt and contaminants in the water are left in the bowl, resulting in clean water in the cup. The experiment aids in understanding the fundamental concepts of solar stills and how they may be used to purify water in isolated places or during survival scenarios where access to clean water is limited.

Theorists who emphasize the discontinuity of development maintain that growth occurs in distinct stages.
Answers
Piaget's cognitive emphasize on the discontinuity of development that growth occurs in distinct stages.
What theories emphasize discontinuous development?The discontinuity sees development as more abrupt a succession of changes that produce different types of behaviors in different age at specific life periods is called stages. Biological changes provide the potential for occurrence of these changes. Period theories which emphasize discontinuous disruption, assume that developmental change often occurs in distinct stages that are qualitatively different from each other, and in a set, universal succession. The classical theories of Freud, Erikson, Piaget, and Kohlberg are called stage theories. Theories of discontinuously emphasizes the insensibility, defense mechanisms, and effect of the id, ego, and superego. Discontinuous are clear stages of development.

Answers
Sieve elements are the phloem cells that are still alive when they reach adulthood but have essentially no organelles left.
Sieve elements are alive at maturity but lack some organelles, such as a nucleus, in comparison to tracheary elements, which have just primary cell walls (and consequently thicker overall cell walls).
Thin-walled cells called sieve elements typically don't have nuclei but are nonetheless alive at maturity despite having a significantly altered protoplast. .The primary walls of parenchyma cells are thin, and they typically continue to live after reaching maturity. The primary type of elongated photosynthate-conducting cell in vascular plants' phloem is known as a sieve element. Sieve regions, which are thinner, circular to elliptical portions of the wall, are present in the walls of sieve elements.

Rats are endothermic (warm blooded) animals. Explain why the physiology of a perch (an exothermic or cold blooded animal) would not support the metabolic needs of a rat.
Answers
They can readily adjust to any maximum temperature, allowing them to survive there. Rats were toasty endothermic animals. As a result, a rat's physiological needs wouldn't be met by the physiology of perches.
Animals having cold blood are those that are unable to adjust their internal body temperature in response to environmental changes. They are unable to endure high temperatures. Reptiles, fish, and other cold-blooded creatures are examples.
Animals with warm blood were those that have the ability to control and maintain a consistent body temperature.

Nervous tissue is not found in plant instead they have some different system to respond to stimuli.
Biologists are aware that there are additional ways to process information in addition to our neurological systems and those of other animals, including fish. Plants can react to stimuli despite not having neural systems. For instance, when an aphid bites a leaf, the plant responds by sending an electrical signal from leaf to leaf instructing it to begin defending itself.
However, it's crucial to remember that a plant does not necessarily feel pain when it reacts to injury.
Plants lack nociceptors, the particular receptor types that are hardwired to respond to pain, in contrast to humans and other animals. They naturally lack the brains essential to convert such sensations into actual experiences since they also lack brains.

Answers
Passive transport carries molecules from the more concentrated side to the less concentrated one, while active transport carries molecules against their electrochemical gradient, needing the energy to do it.
Note: Since the image is not attached and I could not find it, I will define active and passive transport and attach an image with cells, molecules, and arrows indicating molecule motion for each transport case.
What are active and passive transport?Active and passive transport are two ways in which substances can move through the plasmatic membranes.
Passive transport occurs in favor of an electrochemical gradient and does not need energy to move because molecules move from the more concentrated side to the less concentrated one.
Simple diffusion and facilitated diffusion are two types of passive transport.
On the contrary, active transport moves molecules against their electrochemical gradient. This means that molecules move from the concentrated side to the more concentrated one. This process needs the energy to occur.
In the attached image you will find two scenarios. One of them is passive transport and the other one is active trasport. You should notice the differences in substances concentrations at each side of the membrane, and the arrow direction.
