<span> because if the shape of the enzyme changes it may not function or it may function differently.
hope this helps</span>
<h3><u>Connective tissue:</u></h3>
It is the layer under the epithelial tissue in the body. It is stronger than epithelial tissue and is found in many organs. It provides protection.
<h3><u>Epithelial tissue:</u></h3>
It covers the outside of the body like a veil. located in the outermost part of the body. Protects the body against microbes and infections.
<h3><u>Muscle tissue:</u></h3>
It is located in the joint areas and forms the support and movement system. It allows us to make bodily movements.
<h3><u>Nervous tissue:</u></h3>
It is the fastest communication tissue. It allows us to feel pain and the sense of touch. It is impossible to repair this tissue after it is damaged. It causes paralysis. It is very important as it plays a role in the activity of neural transmission.
Fewer hydrogen ions will be pumped into the Thylakoid when photosystem II being exposed to less sunlight more glucose molecules will be produced.
Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature. It produces atmospheric oxygen to catalyze the photo-oxidation of water by using light energy. It oxidizes two molecules of water into one molecule of molecular oxygen.
Photosystem II the energy derived from absorption of photons is used to split water molecules to molecular oxygen and protons. The most important function of photosystem II (PSII) is its action as a water-plastoquinone oxido-reductase. At the expense of light energy, water is split, and oxygen and plastoquinol are formed.

Answer:
Answer is option A.
Vestigial features are fully developed and functional in one group of organisms but reduced and function less in a similar group.
Explanation:
- Vestigial structures are anatomical features such as cells, tissues or organs in an organism that are previously functional and performed some important functions in the organism but no longer serve any functions in the current form of the organism and become useless as a result of a large evolutionary change. Examples include the coccyx or the tailbone in humans, the pelvic bone of a snake, wisdom teeth in humans, nipples in human males, the wings of flightless birds such as kiwi, ostrich, etc.
- Homologous features are the features that are similar in different organisms having similar embryonic origin and development and are inherited from a common ancestor that also had that feature. Also, they might have different functions. An example is the presence of four limbs in tetrapods such as crocodiles, birds, etc.
- Analogous features are the features that are superficially similar in different organisms but had separate evolutionary origins i.e., different in origin, but similar in function. An example includes the wings on a fly, a moth, and a bird where the wings were developed independently as adaptations to perform the common function of flying.
- Polygenic features are the traits or features that are controlled by multiple genes that are located on the same or different chromosomes and are also affected by the environment. These features do not follow Mendel’s pattern of inheritance and are represented as a range of continuous variation. Examples of polygenic traits or features include skin color, height, hair color, eye color, etc. For example, there is wide variation in the human skin color (from light to dark) and height (short or tall or somewhere in between).
- Sympatry describes a species or a population that inhabit the same geographic region at the same time. In sympatric speciation, new species are evolved from a surviving ancestral species while both the species inhabit the same place at the same time i.e., in a single population, reproductive isolation occurs without geographic isolation.
Repetition Practice interferes with the ability to learn new information is true.
It is impossible to overstate the value of repetition. In fact, it needs to be emphasized again how important repetition is as a learning tool. It enables the transfer of a conscious skill into the subconscious, freeing up working memory and enabling the acquisition of new skills. Repetition gives kids the practice they need to acquire new skills, so it's a good thing. Repetition helps kids learn faster, builds confidence, and fortifies the neural connections in their brains that support learning. Practice doesn't always make perfect while learning a new skill. Zachariah Reagh and Michael Yassa, neurobiologists at UC Irvine, discovered that while repetition improves the factual content of memories, it can decrease the amount of detail associated with such memories.
