Answer:
- Eukaryotes are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
- Organisms that contain only one cell and do not contain a nucleus or membrane-bound organelles are known as prokaryotes.
Explanation:
According to their structural and functional complexity, organisms can be classified into eukaryotes and prokaryotes.
Eukaryotic organisms are formed by cells that have a true nucleus -where DNA is located- and specialized structures called organelles, with a system of endomembranes that compartmentalize the intracellular space. These organisms are usually pluricellular, given the ability of eukaryotic cells to group together to form tissues. Prokaryotic organisms are single cells, lacking a nucleus - genetic material is scattered in the cytoplasm - and do not possess organelles. The prokaryotic cells that form these organisms are incapable of binding together, so they do not form tissues.Some unicellular organisms are prokaryotic cells, like some parasitic microorganisms, such as amoebas.

Marine sponges contain an enzyme that prevents the separation of chromatids during mitosis. Which stage of the cell cycle would be directly prevented by this enzyme
Answer:
The anaphase of the Mitotic phase
Explanation:
During the anaphase, the proteins (cohesins) that bind sister chromatids together are cleaved to produce two identical daughter chromosomes (meaning each chromosome contains the exact copy of the same genetic material). These identical chromosomes are then separated by a structure known as mitotic spindle. Individual mitotic spindle attaches itself to each chromosome which are then pulled to opposite poles/"sides" of the cell.
Thus, if an enzyme is going to prevent separation of chromatids during mitosis, the enzyme would do so at the beginning of this process, preventing the cleavage of cohesins which would prevent the separation of the chromatids and subsequently prevent this anaphase from occurring.
Answer:
interphase

how do chloroplasts get energy from the sun
Answer:
Your welcome
Explanation:
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

How does the sun produce light
Answer:
The Sun produces light by a nuclear reaction and it's called fusion. As atoms of hydrogen combine to form helium, they produce vast amounts of heat and light. Sunlight appears white, but it contains a mixture of all the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.
Explanation:

Which of the following characteristics suggests that whales evolved from terrestrial animals?
Answer:
The traditional hypothesis of cetacean evolution, first proposed by Van Valen in 1966, was that whales were related to the mesonychids, an extinct order of carnivorous ungulates (hoofed animals) that resembled wolves with hooves and were a sister group of the artiodactyls (even-toed ungulates).
Is the definition of synthetic? Is it not real or a copy
Answer:
Explanation:
Synthetic is something that is not made from natural materials but rather made from the synthesis of other materials in a lab. This is mostly done in clothing where you have some natural materials like cotton and other materials that are synthetic. This doesn't mean it is not high quality. It is actually preferable for some sports for example to wear synthetic clothing instead of cotton.

Suppose a scientist identifies a rocky planet with a thin atmosphere in a different solar system. Based on the characteristics of planets in our solar system, what might the scientist predict?
A. Like Neptune, the planet has a layer of methane gas
. B. The planet is likely to have
many moons
.
C. The planet is close to its sun the way Mercury is close to the sun in our solar system
D. A year on the planet is likely to be many times longer than a year on Earth.
Answer: The correct option is C.
The planet is close to its sun the way Mercury is close to the sun in our solar system.
Explanation:
Solar system consists of the Sun and the eight planets, dozens of moons, asteroids,comets, meteoroids. The names of the eight planets includes:
-- Mercury
-- Venus
-- Earth
-- Mars
-- Jupiter
-- Saturn
-- Uranus and
-- Neptune.
Mercury is a rocky planet with a thin atmosphere. It is the smallest terrestrial planet and the closest to the sun. It is said to have a thin atmosphere because it lacks hydrogen. The atmosphere gets thinner as one moves further away from the planets surface.
Mercury is a rocky dense planet because its composed mainly of iron and nickel with an iron core. It is also covered by a thin layer of tiny particle silicates.
Therefore the rocky planet with a thin atmosphere identified by the scientist must be a planet that is close to its sun the way Mercury is close to the sun in our solar system.
Analogous structures often develop through the process of _____ evolution, rather than a close evolutionary relationship.
Answer:
The correct answer is - convergent evolution.
Explanation:
The convergent type of evolution involves the process in which non-related organisms evolved independently and still develop similar kinds of traits or structures due to factors such as ecological or environmental conditions. This environmental condition could be an ecological niche or issues faced by the organisms which force them to adapt accordingly.
For example, dolphins and shark look similar but are different organisms. Analogous organs or structures arise due to the convergent evolution as they have different ancestry still shows structures similar to one another.

what 3 interactions does the endocrine system rely on?
Hormones are used by the endocrine system to elicit responses from target cells. These hormones are produced in specialized glands located far from their intended target and travel through the bloodstream or intercellular fluid. And also the gland and receptor cell.
What is endocrine system?The endocrine system is a web of glands and organs. It controls and coordinates your body's metabolism, energy level, reproduction, growth and development, and response to injury, stress, and mood using hormones.
The endocrine system is composed primarily of the female ovaries, male testes, pituitary, thyroid, and adrenal glands.
The endocrine system employs hormones to elicit responses from target cells. These hormones are produced in specialized glands far from their intended target and travel via the bloodstream or intercellular fluid.
Glands are organs that produce one or more substances such as hormones, digestive juices, sweat, tears, saliva, or milk.
A hormone receptor is a molecule that binds to a particular chemical messenger.
Thus, gland, hormones and receptor cells are the 3 interactions that the endocrine system rely on.

a liquid that exits the scrotum once meet with high friction and or sexual action that has properties to create a live egg capable of birth
Answer:
semen/seminal fluid
Explanation:
The "semen" consists of sperm cells and other secretions. These secretions come from the seminal vesicles, prostate gland, testicles, epididymis, bulbourethral and urethral glands.
Once the male is aroused (through sexual action), the penis gets larger and this causes the release of the semen from the scrotum (regulates the temperature of the testes). Such process is known as "ejaculation." This fluid has a high potential to make a woman give birth.
