Selective attention is our ability to be conscious of some aspects of our environment while ignoring others. Therefore, the correct statement is option C.

What is selective attention?

Selective attention is the ability of our mind to be conscious of some aspects while ignoring others. In selective attention, our mind focuses on a certain aspect of the environment and filters out the rest of the aspects. Selective attention is useful as it allows one to focus only on the useful information and responds to an important stimulus in an environment.

Selective attention can be affected by various factors such as our dedication to particular interests and goals. For example, while we are driving in heavy traffic, we will only focus on the potential hazards and ignores all the other information, such as education, career, etc.

Selective attention involves top-down and bottom-up processing. Top-down processing involves the use of information, such as knowledge, goals, etc. to retain our attention, while bottom-up processing involves the use of sensory information to capture our attention.

Therefore, selective attention is our ability to focus on only certain aspects of the environment.

The best clue that can be used to decide living thing or not a living thing is the observation of living or dead cells present in the specimen. All the living or dead organisms exhibit cells. Cell is a structural and functional unit of life. The growth and metabolism of living organism are dependent upon a cell. A cell in a life form exhibit organelles and components which are not found in non-living objects

The BEST clue you could use to decide: living thing or not a living thing- is option C. is it made of cells and

The living things have some basic characteristic features of life in them that help in determining if an object or thing is living or nonliving thing. these characteristic can be present in all or some, are as follows:

thus, there is two options only that present in every living organism that are made of cells and presence of DNA, but for DNA one need to investigate thoroughly so the correct answer is - C) Is it made of cells?

Answer:

Centromere

Explanation:

Connects sister chromatids

The structure labelled A in the figure is a centromere.

The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.

The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.

Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted

The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

Answer:

The light reactions of many algae differ from those of land plants because some of them use different pigments to harvest light. Chlorophylls absorb primarily blue and red light, whereas carotenoids absorb primarily blue and green light, and phycobiliproteins absorb primarily blue or red light. Since the amount of light absorbed depends upon the pigment composition and concentration found in the alga, some algae absorb more light at a given wavelength, and therefore, potentially, those algae can convert more light energy of that wavelength to chemical energy via photosynthesis. All algae use chlorophyll a to collect photosynthetically active light. Green algae and euglenophytes also use chlorophyll b. In addition to chlorophyll a, the remaining algae also use various combinations of other chlorophylls, chlorophyllides, carotenoids, and phycobiliproteins to collect additional light from wavelengths of the spectrum not absorbed by chlorophyll a or b. The chromophyte algae, dinoflagellates, cryptomonads (class Cryptophyceae), and the class Micromonadophyceae, for example, also use chlorophyllides. (Chlorophyllides, often incorrectly called chlorophylls, differ from true chlorophylls in that they lack the long, fat-soluble phytol tail that is characteristic of chlorophylls.) Some green algae use carotenoids for harvesting photosynthetically active light, but the Dinophyceae and chromophyte algae almost always use carotenoids. Phycobiliproteins, which appear either blue (phycocyanins) or red (phycoerythrins), are found in red algae and cryptomonads.

ribosomes

The Protein Factory. Plant, bacteria and animal cells all have ribosomes that contain RNA and proteins. Ribosomes translate nucleic acids into amino acids to make proteins. Proteins form enzymes and play a role in every function within cells.

A dorsiventral leaf, also known as a bifacial leaf, is a type of leaf structure characterized by having distinct upper and lower surfaces with different functions and structures.

The upper surface of a dorsiventral leaf is called the adaxial surface, while the lower surface is called the abaxial surface. The adaxial surface is usually dark green and is exposed to more sunlight, while the abaxial surface is typically lighter in color.

This structural asymmetry allows for efficient photosynthesis on the upper surface while minimizing water loss through stomata on the lower surface.

Dorsiventral leaves are commonly found in dicotyledonous plants and contribute to their overall shape and function in terms of light absorption, gas exchange, and transpiration.

Explanation:

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

The overall equation for this pathway is:

1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

nuclear fission

Nuclear power comes from nuclear fission

The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy

In nuclear power plants, neutrons collide with uranium atoms, splitting them.  In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity
