Which term describes the two groups of plants that do not need water to reproduce?
Paleozoic plants
cotyledons
spermatophytes
embryophytes
Spermatophyte is the term that describes the two groups of plants that do not need water to reproduce.
Water is not necessary for fertilization or reproduction in spermatophytes since siphonogamy occurs where the male gametes are transported via the pollen tube. Siphonogamy is a condition in plants in which the male cells are transferred to the eggs via the development of pollen tubes. Seed plants are often siphonogamous.
Spermatophyte is a group of plants including gymnosperms and angiosperms. Gymnosperms are cone-bearing plants, while angiosperms are flower-bearing plants. They reproduce sexually through the means of seeds.
Spermatophytes initially develop pollen for fertilization. The pollen is then transferred to the ovary via pollen tubes, resulting in the production of seeds. Pollen is transferred by vectors like air, any insect, etc. Thus, they do not require water for reproduction.

what happens when a cell outgrows the membrane
Answer:
When the cell outgrows the cell membrane, it breaks, the components go outside and the cell can no longer maintain its functions. That is, such disturbance would make it impossible to maintain homeostasis, it would not be possible to eliminate water and ions, which accumulate inside the cell and cause the rapid loss of the integrity of the plasma membrane.

C) Number of chloroplasts
D) Concentration of nitrogen in the air
Which factor least influences the rate of photosynthesis?
Options :-A) Atmospheric concentration of carbon dioxide
B) Time of day
C) Number of chloroplasts
D) Concentration of nitrogen in the air
Answer :-D) Concentration of nitrogen in the air
Explanation :- Concentration of nitrogen in air is about 78% and it's insert in nature bez neither the planets nor the animals have the ability to break three bonds of N2 molecule (gas ) so any alterations in its concentration will not make any influence in photosynthesis concentration of CO2 make influence in the maximum but it also makes its effect upto some extent and that extent is called the saturation point Time of the day is effects like in morning and Evening photosynthesis is very less in comparison to the photosynthesis in afternoonRate of photosynthesis is directly proportional to number of chloroplast as more the number of chloroplast more will be the photosynthesisThe factor that least influences the rate of photosynthesis is the Concentration of nitrogen in the air. Thus, the correct option for this question is D.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The process of photosynthesis significantly depends on the amount and color of sunlight along with the amount of carbon dioxide because they are the reactants of this reaction while the amount of sugar is delivered as a product of the reaction.
Therefore, the factor that least influences the rate of photosynthesis is the Concentration of nitrogen in the air. Thus, the correct option for this question is D.

Use the drop-down menus to determine which system the following structures belong to. pituitary gland thyroid gland salivary glands
The following glands may be classified by using the drop-down menus:
Pituitary Gland ------ Endocrine Thyroid Gland ------- Endocrine Salivary Gland ------- Exocrine. What do you mean by Glands?A gland is an organ that produces and releases substances that perform a specific function in the body. They perform a key role in the metabolism process.
Endocrine Glands secrete hormones whereas exocrine glands secrete enzymes. The pituitary gland secretes growth hormone, LH, etc, while the thyroid gland secretes thyroxine hormone. So, both of these glands are classified under Endocrine glands. But the salivary gland produces an enzyme called salivary amylases, which leads to the formation of saliva. Hence, it is classified under the exocrine gland.
Therefore, all the above-described glands are classified on the basis of their functions.

Explain how bones, muscles, tendons, and ligaments work together to move a chickens wing
Answer:
If you pull on the bicep muscles of the chickens wing, you will pull on the tendon that connects the muscle to the bone. Then the tendon will pull on the bone that it is attached to and cause it to move.
Without tendons, muscles and bones are independent from one another, so by connecting muscles and bones, whenever a muscle contracts or moves, the bone moves as well. These tendons are known as 'connective tissue'.
The ligaments will allow the bones to move but will keep the bones together in the joint. Muscles surrounding the bone are actually the tissue of the chicken wing that is commonly referred to as the meat.
The ligaments maintain the bones' togetherness in the joint while allowing for movement of the bones. As you can see, moving the chicken wing requires numerous components to work together.
What bones, muscles, tendons, ligaments work together?We can see that the muscles contract and expand the wing in opposite directions by pulling on them. Flexors and extensors are the muscle pairs that cooperate.
A joint bends when the flexor muscle contracts, and straightens when the extensor muscle contracts. The flexor relaxes as the extensor contracts.
Our body's movement and stability are facilitated by the coordinated action of our bones, muscles, and joints. Tendons and ligaments are also crucial in this situation. Ligaments help to hold things in place, and tendons link muscles to bones, so we can move.
Therefore, The bone to which the tendon is linked is then pulled, which moves the bone. Ligaments connect bones to one another.

what is the ideal microbiome?????please help asap
Embracing the complexity of the microbiome means doing away with pat conceptions of its function.
Your body is a habitat to trillions of microscopic organisms known, collectively, as your microbiome. Today, the microbiome is one of the hottest areas of biological research, and for good reason. This body-wide ecosystem not only adapts to our diets, lifestyles, and medications, it's also been shown hold sway over our health. The implications for personalized medicine seem clear – the more we understand about the microbiome, the more we can do to condition, or control it to our liking.
But to what end? To shepherd one's microbiome toward some idealized state of healthiness would first require that such a state exists. What does such a state look like? Nobody knows, because an ideal microbiome is almost certainly an illusion. As science writer Ed Yong opines in today's New York Times, contrary to claims by the probiotic industry and the booming genre of microbiome diet books, any system as "complex, varied, ever changing and context-dependent" as the microbiome will, by its very nature, resist easy categorization:
The microbiome is the sum of our experiences throughout our lives: the genes we inherited, the drugs we took, the food we ate, the hands we shook. It is unlikely to yield one-size-fits-all solutions to modern maladies.
We cling to the desire for simple panaceas that will bestow good health with minimal effort. But biology is rarely that charitable. So we need to learn how tweaking our diets, lifestyles and environments can nudge and shape the ecosystems in our bodies. And we need ways of regularly monitoring a person's microbiome to understand how its members flicker over time, and whether certain communities are more steadfast than others.

Answer:
D
Explanation:
I think it depends on the magnitude of the two velocities. Relative velocity is the time rate of change of relative position of one object with respect to another. If two objects are moving in opposite direction, the magnitude of the relative velocity of one object in respect to another is the sum of the magnitude of the two velocities.
