Do humans depend on photosynthesis?
A: No, humans cannot make food by photosynthesis, so they do not depend on photosynthesis for energy.
B: Yes, all of the food consumed by humans is plants or gets energy from plants, and plants produce their own food through photosynthesis.
C: Yes, but only those humans that avoid meat depend on plants that produce their own food through photosynthesis.
D: No, humans rely on animals for food, and neither humans nor animals depend on photosynthesis for food.
Answers
Answer:
B. Yes, all of the food consumed by humans is plants or gets energy from plants, and plants produce their own food through photosynthesis.
Explanation:
Photosynthesis is a chemical process that plants perform in order to get the energy that they need to survive and grow. The chemical that makes plants green, called chlorophyll, is the molecule that makes this reaction possible. Without photosynthesis, plants would not be able to get energy from the sun. The ability to create plant food from solar energy through photosynthesis is the process that underlies almost all life on Earth.

19) there are two major types of protein kinases according to which amino acids they phosphorylate. what are these amino acids for the two groups?
Answers
Kinases often fall into one of two categories: Either they will phosphorylate the bulkier aromatic tyrosine or the smaller serine and/or threonine, which are frequently interchangeable. Thus, they are suitably known as protein tyrosine kinases (PTKs) and protein serine/threonine kinases (PSTKs) (PTKs).
Protein kinase comes in two primary varieties. Although there are other varieties, serine/threonine kinases make up the vast majority. These enzymes phosphorylate the hydroxyl groups of serines and threonines in their substrates. Additionally, microbes and plants include protein kinases.

how do cells at the end of meiosis compare with cells that have replicated their dna and are about to begin meiosis?

The cells that are produced at the end of meiosis, have half the number of chromosomes and one-fourth the amount of DNA. (option d)
at the end of meiosis, cell division has half as many chromosomes (called haploid), so they will have half as many chromosomes but the same DNA as the parent cell because DNA divides and copies the DNA of the parent cell.
The number of chromosomes and DNA in daughter cells that are produced at the conclusion of meiosis is half that of cells that have already replicated their DNA and are about to begin meiosis, four daughter cells are produced. This indicates that each daughter cell will receive a portion of the DNA that is shared by the parent cells (1/4).

oak trees go into a state of democracy during the winter . Suppose that a forest of oaks grows in that area that begins to experience warmer winters due to climate change . what effect do you think this will have on oak trees? explain
Answers
The dormancy is dependent on the photoperiodism, which is the plant's response to the changes in the length of night and day, and the decreasing temperature in the environment. If the oak trees would experience warmer weather and longer days due to climate change in the winter, then the period of dormancy would be reduced. The tree would remain active as long as the temperature is not low enough to slow down its chemical processes.
A tree or shrub, which literally means oak tree in Latin, belongs to the family of beech trees. The number of living oak species is around 500. As well as being used in the names of unrelated species like Grevillea robusta (silky oaks) and the Casuarinaceae, the common word "oak" is also used in the names of species in allied genera, most notably Lithocarpus (stone oaks) (oaks). Native to the Northern Hemisphere, the genus contains deciduous and evergreen species that grow throughout the Americas, Asia, Europe, and North Africa at latitudes ranging from mild temperate to tropical.

Which phrase names a direct result of hydrogen bonding?
O movement by osmosis
O the bent structure of a water molecule
O the polar ends of a water molecule
O cohesion and adhesion
Answers
The phrase names a direct result of hydrogen bonding is cohesion and adhesion. Option D.
Surface tension is caused by the cohesion of water through hydrogen bonding and the polarity of water. Agglomeration creates high surface tension, requiring a large amount of energy to bind and break water molecules. This makes hydrogen an electrically positive atom because it lacks electrons.
Hydrogen bonds are formed due to the attraction between the oxygen atoms of one water molecule and the hydrogen atoms of another water molecule. A hydrogen bond is formed when the plus end of one molecule is attracted to the minus end of another molecule. This concept is similar to magnetic attraction where opposite poles attract each other. Hydrogen has one proton and one electron.

Which is an example of disturbance and primary succession currently happening on earth?.
Answers
Primary succession, for instance, might take place following the eruption of volcanoes, such as those on Hawaii's Big Island. As lava flows into the water, rock is produced.
Primary succession: What is it?
Primary succession, the initial phase of ecological recovery after a major disturbance, often occurs in an environment devoid of vegetation and other living things. These habitats frequently lack soil because of natural disturbances like lava flows and retreating glaciers.
Contrarily, secondary succession occurs on substrates that had previously supported vegetation before an ecological disturbance. This occurs when less severe disturbances, including fires, floods, and storms, only entirely destroy the local plant life while leaving the nutrients in the soil available for the swift growth of intermediate community species.

The Photosynthesis Light Reactions. The energy from the absorbed light is then used to push protons through a membrane and drive electrons from water to create NADPH. To create ATP, these protons return via ATP synthase. In reality, photosynthesis is divided into two steps: In the light-dependent reactions, the pigment molecule chlorophyll catches light energy in the chloroplast's thylakoid membranes and converts it to chemical energy. Only a membrane protein known as ATP synthase allows hydrogen ions in the matrix space to pass through the inner mitochondrial membrane.
