Describe how the light-independent reactions of photosynthesis/ respiration work. Describe what happens in the light-dependent part of the cycle compared to the light-independent part of the cycle (light reaction/dark reaction)
Answer:Photosynthesis in desert plants has evolved adaptations that conserve water. In harsh, dry heat, every drop of water must be used to survive. Because stomata must open to allow for the uptake of CO2, water escapes from the leaf during active photosynthesis. Desert plants have evolved processes to conserve water and deal with harsh conditions. A more efficient use of CO2 allows plants to adapt to living with less water.
Some plants such as cacti can prepare materials for photosynthesis during the night by a temporary carbon fixation and storage process, because opening the stomata at this time conserves water due to cooler temperatures. In addition, cacti have evolved the ability to carry out low levels of photosynthesis without opening stomata at all, a mechanism for surviving extremely dry periods.

Cactus: The harsh conditions of the desert have led plants like these cacti to evolve variations of the light-independent reactions of photosynthesis. These variations increase the efficiency of water usage, helping to conserve water and energy.
CAM Photosynthesis
Xerophytes, such as cacti and most succulents, also use
phosphoenolpyruvate (PEP) carboxylase to capture carbon dioxide in a process called crassulacean acid metabolism (CAM). In contrast to C4 metabolism, which physically separates the CO2 fixation to PEP from the Calvin cycle, CAM temporally separates these two processes.
CAM plants have a different leaf anatomy from C3 plants, and fix the CO2 at night, when their stomata are open. CAM plants store the CO2 mostly in the form of malic acid via carboxylation of phosphoenolpyruvate to oxaloacetate, which is then reduced to malate. Decarboxylation of malate during the day releases CO2 inside the leaves, thus allowing carbon fixation to 3-phosphoglycerate by RuBisCO. Sixteen thousand species of plants use CAM.

What type of cloning process was used to create Dolly the sheep?
Answer:
nuclear transfer
Explanation:
Hope this helps❤
Answer:
Dolly the sheep was successfully cloned in 1996 by fusing the nucleus from a mammary-gland cell of a Finn Dorset ewe into an enucleated egg cell taken from a Scottish Blackface ewe. Carried to term in the womb of another Scottish Blackface ewe, Dolly was a genetic copy of the Finn Dorset ewe.

When is creatine phosphate being metabolized within cellular respiration?
Answer:
Creatine phosphate, a high‐energy molecule stored in muscle cells, transfers ... ATP is then generated from glucose by cellular respiration.Explain the process involved in muscle metabolism during aerobic exercise ... Pyruvate is continually processed into lactic acid.
Explain how the sense of smell works on a molecular level. Be sure to describe what is happening in the brain as well?
Answer:
The smell is one of the senses that is created by the small molecules that are released by the food, aromatic substance, or any substance into the air. When we inhale during the breathing process these small molecules enter our nose and trap in tiny hair of the nose.
These molecules dissolves in mucus present in the nose to reach the specialized receptor cells known as olfactory receptor neurons. These neurons detect the smells and send the information directly to the brain to the olfactory bulbs that work to detect the smell.
Nose can recognize tests which are not part of a Test class, derived from a Parent class. State true or false.
Answer:
the answer is True
Qil: Which of the following best explains why both plant and animal cells contain cell membranes? A Both animal and plant cells have cell membranes to act as the site of protein synthesis. B Both animal and plant cells have selectively permeable cell membranes to control which substances can enter and leave the cell. C Both animal and plant cells have cell membranes to store and organize their genetic material. D Both animal and plant cells have cell membranes that contain cellulose to provide structure and support for the cell. E This is incorrect; only animal cells have cell membranes.
Almost all the South American and Central American
Indlans have Rh-positive, type O blood. Note that there
Is no significant biological advantage to this blood type.
Which mechanism best explains these facts?
O founder's effect
Ogene mutation
Onatural selection
Answer:
O founder's effect
Explanation:
A founder effect can be defined as the loss of genetic variation when a new population is established from a few individuals. This process is known to increase the frequency of particular gene variants (alleles) at different loci when they are selectively neutral (or nearly neutral), and thereby such genes are fixed by genetic drift (i.e., through the random sampling of founder individuals). Interestingly, it has been discovered that the majority of South American and Central American Indians are nearly exclusively in the O blood group, which has been further associated with random genetic drift and a founder effect.
Which of the following definitions is the best definition of a mutation?
A mutation is a permanent change in the order or bases in DNA.
A mutation is a temporary change in the way a cell carries out mitosis.
A mutation is a temporary change in the order of bases in the DNA.

Explanation:
How does an iron nail change after being exposed to the oxygen in the air over a long time? Question 24 options: It burns It decays It molts It rusts
Answer:
It rusts
Explanation:
Iron is a chemical element that has the ability to RUST when exposed to air and water. Rusting is actually a prolonged chemical process or change that results when iron reactively combines with water and oxygen in the atmosphere to from hydrated (III) oxide in a process called OXIDATION. This compound is behind the color change of the metal.
According to this question, a nail made of iron will change after being exposed to the oxygen in the air over a long time by RUSTING via the oxidative reaction of the iron constituent of that nail with oxygen.
Which of the following best describes angiosperms?

A man has hemophilia, but his parents do not. Using H for normal and h for hemophilia, give the genotype of his father, mother, and himself in that order.
Answer: refer to the attached image for the genotypes.
Explanation:
Hemophilia is a blood clotting condition in an X-linked recessive pattern that is inherited from parents by offspring. In order to be expressed in a female, the mutation must have both X chromosomes. In males, only the one X chromosome that he has to transmit needs to be present.

Which process occurs within the mitichondria
Answer: The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH.

What is the main benefits of being vegetarian?Vegetarian person plays a vital role in maintaining the food chain of an ecosystem. Vegetarian person has always have low density-lipoprotein cholesterol level, lowers blood pressure and lower rates of hypertension and type 2 diabetes as compared to non-vegetarian person.
Vegetarians have less chance suffered very much with obesity because in vegetable there has been very less amount of fat due to this they doesn't suffer with obesity so being a vegetarian is very helpful for health.
Being vegetarian has not easy because form the point of view of nutrients you must intake proper vegetable to manage you nutrients needs if you do not have than you suffer with nutrients deficient. So, you have to be very carefull for your diet.
