Answer:
1. Protein Channel pumps ions and other substance through the cell membrane
2. Hydrophilic - Packed love water
3. Hyphobic - Hate water
4. Phospolipid bilayer - the cell membrane
Explanation:
One type of molecule (or a few molecules that are closely related) is all that a channel will accept for transit.
What role of channel protein and membrane component?A channel protein is an illustration of a transport protein; it serves as a pore in the membrane to permit water molecules or small ions to move through quickly.
Water may quickly diffuse through the membrane thanks to aquaporins, which are proteins that function as water channels. Ion channel proteins enable unrestricted ion transport across the membrane.
Channel proteins span the membrane, forming hydrophilic tunnels that let their target molecules diffusely pass through.
For instance, channel proteins enable the passage of bigger molecules like glucose as well as ions like sodium, potassium, and calcium through the membrane.
Therefore, Large or charged molecules can pass across the membrane to channel proteins.

What type of tissue comprises wood in woody stems?
Answer: Woody plants have an extra layer of protection on top of the epidermis made of cork cells known as bark. The vascular tissue of the stem consists of the complex tissues xylem and phloem which carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles.
Explanation:
Bark protects woody plants' epidermis with cork cells. Xylem makes up most of a stem's wood, while phloem is in the bark.
What makes up most of a woody stem?Many shrubs and plants have woody stems. The most notable distinction between the two kinds of stems is that woody stems are mostly made of firm cork rather than soft epidermis. As the cork ages, it develops bark and hard woods.
The inner and outer derivative products of the vascular cambium are secondary xylem (wood) and phloem. The primary constituents of xylem are dead cells with thicker cell walls rich in cellulose, hemicelluloses, and lignin. Xylem serves as the plant's mechanical support system and conductor of water and minerals.

Which of the following is not a future impact of global warming?
Less land
Less methane
More drought
Human migration
Answer: Less methane
Explanation:
The following is not a future impact of global warming: less methane, which is present in option B, as methane is a potent greenhouse gas that contributes to global warming when released into the atmosphere.
Global warming can contribute to sea-level rise, which may lead to the loss of coastal areas and low-lying land due to increased flooding and erosion. Rising temperatures can alter precipitation patterns and lead to increased evaporation, which can result in more frequent and severe droughts in certain regions. Global warming can disrupt ecosystems, affect agriculture, and alter living conditions in vulnerable areas, potentially leading to increased human migration as people seek more habitable and stable environments.

All producers and autotrophs go through photosynthesis?
False ?
True ?
Because autotrophs produce their own food, they are sometimes called producers. ... Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
true or false? most of the cells in a mushroom contain haploid nuclei.
Answer:
True
Explanation:
Most of the cells in a mushroom contain haploid nuclei. a mushroom consists mainly of hyphae that are heterokaryotic, which means they have two distinct haploid nuclei per cell; these nuclei may fuse in specialized cells called basidia and become diploid in preparation for meiosis and spore production.

Triploblastic animals have three germ layers. They are the following:
The outer layer is called the Ectoderm.The inner layer is called the Endoderm.The middle layer is called the Mesoderm.What do you mean by germ layers?The germ layers may be defined as a group of cells that develops in an embryo. These germ layers are responsible for the generation of organs and tissues as the embryo develops.
The ectoderm forms the brain, spinal cord, eye, skin, and hair. The mesoderm is responsible for the formation of the notochord, bone, circulatory system, muscles, and connective tissues. The endoderm leads to the formation of the stomach, liver, pancreas, lungs, and urinary bladder.
Therefore, Triploblastic animals have three germ layers. They are ectoderm, mesoderm, and endoderm.

the process by which external dna is transferred to a different bacterial cell is referred to as __.
Answer:
Transduction
Explanation:
Transduction is the transfer of DNA from one bacterium to another by means of a bacteria-infecting virus called a bacteriophage.
Once connected, the two cells are brought into direct contact, and a conjugal bridge forms through which the DNA is transferred from the donor to the recipient.
Transduction is the process of transfer of genetic material (DNA) between bacterial cells mediated by bacteriophage viruses.
What is transduction?It is the process of genetic transfer from a donor cell to a recipient cell.
It is the introduction of an exogenous nucleic acid into a cell by means of a virus, originally designated the transfer of genetic material between bacteria by means of a phage.
Therefore, we can conclude that transduction is the process of transfer of genetic material (DNA) between bacterial cells mediated by bacteriophage viruses.

Do animals have the right to a certain quality of life?
Explanation:
All Animals have EVERY right to a good quality of life! It is humans with a typical human arrogance that decide who lives, who dies, who is food and who is not and how they will live and be killed. We even have Animal Protection laws for dogs, cats and “pets” and farm animals are treated like dirt, having very few protections! If you did to your dog what you do to pigs you would go to jail! Discrimination and arrogance taken to the nth degree! Since humans subject Animals to the existence humans choose and nobody ever asked a cow, a pig, a hen or any other animal how they want to live their life I think it can qualify as “Slavery”.
