Answer:
B. ATP & NADPH
Explanation:
fruits and vegetables are full of energy. Energy in the form of glucose. The energy from sunlight is briefly held in NADPH and ATP, which is needed to drive the formation of sugars such as glucose.
As Melvin Calvin discovered, carbon fixation is the first step of a cycle. The Calvin cycle transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transport chain, excited electrons lose energy to NADPH and ATP. In the Calvin cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose.
The Calvin Cycle uses ATP and NADPH to produce glucose. These energy carrying molecules are created during the light reactions of photosynthesis.
Explanation:To produce glucose during the Calvin Cycle, the molecules ATP (Adenosine Triphosphate) and NADPH (Nicotinamide Adenine Dinucleotide Phosphate) are utilized. These two molecules are vital energy carriers and are produced during the light reactions of photosynthesis. The energy they carry is used to convert carbon dioxide which is absorbed by the plant into glucose (a type of sugar). For example, substances like Glyceraldehyde-3-phosphate (GA3P) are produced as part of the Calvin Cycle. GA3P is effectively half a glucose molecule and through two cycles of the Calvin Cycle one molecule of glucose is generated utilizing the energy from ATP and NADPH.

C. They use fermentation to make ATP.
D. They live in oxygen-rich settings.
Answer:D
Explanation:good guess
Answer:
The correct answer is option D.
Explanation:
Organisms or particularly species that survive in the absence of free oxygen are called anaerobes or anaerobic species. Some of the anaerobes grow only in the absence of free oxygen are called strict or obligate anaerobic species.
Anaerobic species only form 2 molecules of ATP for every 1 molecule of glucose, while aerobic cells produce 38.Fermentation metabolism permits these species to survive in some of the most extreme environments.
Thus, the correct answer is option D.
Which of the following correctly compares steroid and nonsteroid hormones
A. Nonsteroid hormones enter the nucleus and affect protein synthesis while steroidal hormones do not. B. Neither steroid nor nonsteroid hormones enter the cell membrane. C. Steroid hormones bind to receptors on the outside of the cell and rely on secondary messengers while nonsteroidal hormones do not. D. Steroid hormones enter the nucleus and affect protein synthesis, while nonsteroidal hormones do not.
Answer:
The correct answer is option D.
Explanation:
Steroid hormones are basically are lipid-soluble molecules and derived from cholesterol. Steroid hormones pass through cell membranes because they're lipid soluble, and attach to a receptor that is present inside the cell, entering the nucleus, binding to DNA, and beginning gene transcription and translation and produce protein.
Nonsteroid hormones are water soluble hormones that do not enter the cell membrane but bind to cell membrane receptors that produce a chemical signal inside the target cell.
Thus, the correct answer is option D.
The correct comparison between steroid and nonsteroid hormones is C. Steroid hormones bind to receptors on the outside of the cell and rely on secondary messengers while nonsteroidal hormones do not.
Explanation:Steroid hormones, which are derived from cholesterol, are lipid-soluble and can diffuse through the cell membrane to bind to intracellular receptors in the cytoplasm or nucleus. This binding triggers the movement of the hormone-receptor complex to the cell nucleus and the activation of specific genes, leading to the synthesis of proteins.
On the other hand, nonsteroid hormones, such as amino acid-derived and polypeptide hormones, are not lipid-soluble and cannot directly enter the cell. Instead, they bind to receptors on the outer surface of the plasma membrane, triggering signaling pathways and intracellular activity, but do not affect protein synthesis or enter the nucleus.

Environmentalists are monitoring an area of tropical forest that is being deforested because of human activities. The graph here shows the scientists predictions based on the data they have collected. How is the ecosystem likely to change as a result? Select the two correct answers.
A) Species extinction - This is because animals will lose their homes and will eventually, slowly die out.
and
D) Reduced oxygen - Trees provide us with oxygen
I hope this helps you. ☺
Answer:
The letters A and D are correct.
Explanation:
As you can see from the chart above, due to the constant deforestation of the tropical forest the number of trees in this region is decreasing every year.
As a result of this deforestation, many species will be extinct. First, it will be possible to extinguish many species of plants, or with a reduced population number. In addition, many animals have plants as their natural habitat, when the plant is cut these animals are left without their habitat, exposed to predators and other problems that can cause their extinction.
We cannot forget that plants are one of the main providers of oxygen in our atmosphere, through photosynthesis. If the plant population decreases, the amount of photosynthesis performed decreases and, as a consequence, the amount of oxygen released into the atmosphere decreases.

Types of Roots : Roots are of two types viz. (a) Tap roots(normal or main) and
(b) Adventitious roots.
(a) TAP ROOT-Here the radicle prolongs directly to form a main primary roots when the primary root becomes stronger and persistent, it forms the tap root e.g. roots of dicotyledonous plants.
Primary root forms tap root, its lateral branches are secondary roots; branches of secondary roots in turn produce tertiary roots and so on. The tap root with its branches forms the tap root system.
The two-step process by which cells read a gene and produce a string of amino acids that will eventually become a protein is called: ____________________ and ______________________
Answer:
transcription and translation
The two-step process by which cells read a gene and produce a protein is called transcription and translation. These two processes form the basis of gene expression whereby genetic information is transferred from DNA to RNA (transcription), and then from RNA to protein (translation).
Explanation:The two-step process by which cells read a gene and produce a string of amino acids that will eventually become a protein is called transcription and translation.
In the process of transcription, a strand of messenger RNA (mRNA) is synthesized, which is complementary to the gene of interest. This is carried out in the nucleus of the cell where a region of the DNA unwinds and the two strands separate. The gene's DNA code is then transcribed to form the complementary stand of mRNA.
After transcription, the next step is translation. Here, the codons (triplets of nucleotides) on the mRNA are translated using another type of RNA called transfer RNA (tRNA) into a sequence of amino acids. This happens in the ribosomes, the 'desk', where the mRNA sequence is read and translated into the amino acid sequence of the protein that it encodes. This two-step process is collectively referred to as gene expression or the central dogma of molecular biology.

Answer:
yes, bird have wings, and so do insects, as well as some birds communicate with each other, as do some insects, and although this may not be similar to each other, they are very interesting, that the birds feathers are actually heavier than there feathers, because their bones are hollow, and insects have an exoskeleton, so basically, they both have interesting bone features
Explanation:
Although birds and insects share some structural similarities like exoskeletons and compound eyes, these similarities are more often seen as examples of convergent evolution rather than proof of close relatedness.
Explanation:Yes, birds and insects do share some structural similarities, but this does not necessarily suggest they are closely related. They both have exoskeletons, although insects have a hard protective covering all over their bodies, while birds just have it on their wings (feathers). Additionally, both groups have compound eyes and they both have wings for flight, though they function and are structured differently. Birds have wings are developed as limbs with bones and muscles covered by feathers, whereas insects have their wings as an extension of their exoskeleton. These similarities are more often seen as examples of convergent evolution, where different species independently evolve similar traits, rather than evidence of close relatedness.
