The energy from the photosynthesis equation is transferred into sugars, where it is stored in the chemical bonds of glucose and used by organisms in ecosystems.
The energy shown in the equation of photosynthesis is transferred into sugars. During photosynthesis, plants convert the radiant energy from sunlight into stored chemical energy. This energy is captured through a series of reactions that result in the production of glucose and oxygen. The energy is stored in the chemical bonds of glucose, a type of sugar, which organisms use to perform various functions such as movement, growth, and reproduction. This stored energy can then enter ecosystems and continually be transferred from one organism to another through the food chain.

The offspring of a particular cross are 100 percent heterozygous for tallness. What were the most likely genotypes of the parents?
Tt ´ tt
Tt ´ Tt
tt ´ tt
TT ´ tt
Answer:
Option D, TT ´ tt
Explanation:
Allele for tallnes "T" is dominant over the recessive allele "t"
The genotype of a heterozygous tall offspring will be "Tt"
When a cross is carried out between "TT " and "tt" , the following offspring are produced -
T T
t Tt Tt
t Tt Tt
All the offspring have genotype "Tt" which is a heterogyzous allele pair.
Since "T" is dominant over "t", all the alleles would be heterozygous tall.
Thus, in order to produce 100 percent heterozygous tall offspring, the cross must be carried out between "TT" and "tt".
Option D is correct

Why do living things need energy
Explanation:
All living things consist of cells in their bodies. There are trillions of cells in a human body. Cells form the structure of the body. Cells cannot survive on their own, because they continuously need energy to perform different functions of the body of the living things. Functions of living things may include growth, repair, reproduction, movement, etc. So cells take nutrients from the food which a living thing eats, convert those nutrients into energy and then use that energy to perform the above mentioned tasks. So Energy is needed by all living things to stay alive.
Living things need energy for growth, metabolism, reproduction, and maintenance.
Life requires energy. Growth requires energy to synthesise chemicals and develop complex structures. Energy is needed to break down foods, create ATP (adenosine triphosphate), and perform cellular functions in metabolism. Gametes and offspring require energy, whether asexual or sexual.
Maintaining body temperature, muscular contractions, nerve impulses, and organ and system function requires energy. Energy fuels biochemical reactions and physiological functions that enable organisms to survive, thrive, and perform the many life processes. Living creatures need energy to survive.

C.The closest living relatives of humans
D.Both a and b
The closest living relatives of humans are chimpanzees; they are not directly our ancestors nor less evolved than us. Instead, both species have been diversely evolving from a common ancestor over millions of years.
Explanation:Chimpanzees are in fact C. The closest living relatives of humans. Humans and chimpanzees belong to the same family, Hominidae, but are part of different genera.
Despite certain similarities, Chimpanzees are not considered more or less evolved than humans. All species are adapting and evolving to best survive in their particular environments, so it is inaccurate to rank one as 'more evolved'.

Explanation:
They are the producers in the ecosystem.
Autotrophs are organisms that produce food food from sunlight or from inorganic substances via chemical processes.
They obatin their energy by converting very simple materials into complex and useful organic compounds for use in the ecosystem. One of such process is photosynthesis in which green plants uses sunlight and carbondioxide to produce glucose for their nourishment. Another of such process is chemosynthesis.
Most heterotrophs(consumers) relies on this source of energy for their own survival and nourishment.
what cause for the different seasons on earth
Answer:
Tiltation of the earth
Explanation:
Seasons occur because of the tiltation of the earth and is tilted at an angle of 23.5°. The earth continuously moves around the sun in its elliptical path. Due to this, the sunlight is incident on the earth at different times causing the four types of seasons namely, spring, autumn, winter and summer.
When the earth's imaginary axis of rotation is tilted towards the sun, then the summer season occurs and the opposite side experiences a winter season. During the summer season, the earth is farthest from the sun and this position is called Aphelion whereas during winter the earth and the sun are at its closest position and this is known as the Perihelion.
Since the earth comes closer to the sun in winter, it should experience hotter weather but it experiences cold weather due to its tiltation.
What part of the brain is highlighted in the diagram below?
Answer:
That is the cerebellum.
Explanation:
It‘s main functions are balance + coordination.
The highlighted part represents the cerebellum.
What is cerebellum?The cerebellum, sometimes known as the "small brain," is a structure that lies underneath the occipital and temporal lobes of the cerebral cortex in the back of the brain. Although the cerebellum makes up only around 10% of the brain's overall volume, it is home to more than 50% of the brain's neurons.What is the function of cerebellum?The following processes are carried out by the cerebellum:
Maintaining posture and balance- Making postural changes to keep one's equilibrium depends on the cerebellum. It modifies orders to motor neurons to account for changes in body position or variations in the stress on muscles using information from vestibular receptors and proprioceptors. Balance issues are common in patients with cerebellar impairment.2. coordination of free-will actions -
The majority of actions are made up of several different muscle groups working together and with precision timing. Coordinating the time and force of these many muscle groups to produce fluid limb or body motions is one of the cerebellum's main roles.3. Neuromotor abilities
Motor learning depends on the cerebellum. Through a process of trial-and-error, the cerebellum is crucial in adapting and fine-tuning motor programming to produce precise motions (e.g., learning to hit a baseball).4. cognitive processes

Could a cell be the size of an elephant? Explain your answer
Answer:
no
Explanation:
actually cells are the smallest unit if life and there so small that you need a microscope to see them so they can't be the size of an elephant
A cell could theoretically grow to the size of an elephant, but it would not be practical due to the decrease in the cell's surface area to volume ratio. This would prevent efficient nutrient uptake and waste removal, resulting in cell death.
Explanation:In theory, a cell could grow to an extremely large size. However, in practice, this would be highly impractical due to the surface area to volume ratio of a cell. This ratio determines how efficiently a cell can exchange materials with its surroundings. As a cell grows larger, its volume increases much more rapidly than its surface area. If a cell were the size of an elephant, this ratio would be so small that the cell would not be able to get enough nutrients or remove waste efficiently, causing it to die. Therefore, a cell could not realistically be the size of an elephant.

glycolipids and glycoproteins function as __ in the cell membrane
enzymes
cell recognition
pumps involved with active transport
exit points for water passing out of the cell by osmosis
Answer:
cell recognition components
Explanation:
glycolipids and glycoproteins function as cell recognition components in the cell membrane.
glycolipids and glycoproteins refer to lipid and proteins on the cell membrane surface that often have short carbohydrate chains protruding out from the cell surface.
glycolipids and glycoproteins function as cell recognition in the cell membrane.
In the complex mosaic structure of the cell membrane, glycolipids and glycoproteins are embedded, presenting carbohydrate chains on the extracellular surface.
These carbohydrate chains participate in cellular recognition processes, allowing cells to identify and communicate with each other. This recognition is vital for processes like immune responses, tissue development, and the maintenance of bodily functions.
Cell recognition is not only crucial in physiological processes but also in disease defense. For instance, immune cells use recognition to distinguish between the body's cells and potentially harmful invaders such as bacteria or viruses. This mechanism forms the basis of the immune response.
Conversely, glycolipids and glycoproteins do not primarily function as enzymes or pumps involved in active transport. Enzymes are typically proteins that catalyze chemical reactions, facilitating metabolic processes within the cell.
Active transport involves specialized proteins (pumps) that move molecules across the membrane against their concentration gradient, requiring energy.
Furthermore, they are not the exit points for water passing out of the cell by osmosis. Osmosis, the movement of water across a semipermeable membrane, is regulated by specific proteins like aquaporins.
These proteins create channels for controlled water movement, playing a critical role in maintaining cellular hydration and osmotic balance.

you have a 12 sided cube that is numbered from 1 to 12. What is the probability of rolling a five?
Answer:
1/12
Explanation:
Formula for calculating probability:
Probability of an outcome A =
Number of favorable outcomes of A / Number of possible outcomes
P ( A ) = number of favorable outcomes to A / total number of outcomes
⇒ The number of times 5 can appear when you roll the 12 sided cube once is one time = 1
⇒ The total number of possible outcomes is 12 - meaning you can roll any number between 1 - 12 when you roll the dice once. = 12
Therefore the probability of rolling 5 = 1 /12
Probability = 1 / 12
hope this help and brainiest please. thx
Answer:
1/12
Explanation:
Probability is the branch of mathematics where the chance of an experiment being calculated is calculated. It is through it that one discovers the possibility of a coin making heads or tails or the chances of landing on the Moon.
To do the probability calculation, it is necessary to divide the number of probable results, by the number of possible results. In the dice game that was shown in the question above, you want side 5 of the dice to face up, this is the probable result that is equal to 1. However, there are 12 sides to the dice and any one of them can fall upwards , they are the possible results, which are equal to 12.
So we can confirm that the probability in this case is 1/12.

The statement "oceanic conditions determine human activities" may be interpreted in many ways.
Oceanic conditions determine human activities in that the moon cycle influences the tide. As the moon cycle is said to greatly influence human activity, and the tide changes as the moon does, it may also be concluded that the tides have a similar influence on human activity.
Explanation:
The way humans treat the Earth and the Ocean depends on how the ocean will be and it's conditions. If people keep producing more and more waste soon humans will be forced to put the garbage in the ocean because there will be no more room in landfills. If humans think about how there actions are affecting earth and the Ocean then there can be a big change for the better.

Answer:
While crenation occurs in animals cells, cells that have a cell wall cannot shrink and change shape when placed in a hypertonic solution. ... Instead, the protoplasm shrinks, leaving gaps between the cell wall and cell membrane. The cell loses turgor pressure and becomes flaccid.
Explanation:
I thick that can help you it help me.
Key biological terms like haemolysis, plasmolysis, crenation, turgidity, and flaccidity primarily refer to the effects of different solutions on cells. Haemolysis and crenation involve animal cells while plasmolysis, turgidity, and flaccidity affect plant cells.
The definitions for the following are:
Haemolysis: This occurs in red blood cells when they are placed in a hypotonic solution, causing them to swell and burst due to the influx of water.Plasmolysis: This is the process by which the cell membrane detaches from the cell wall and constricts the cytoplasm when a plant cell is in a hypertonic solution, resulting in the cell losing its turgor pressure and becoming plasmolyzed.Crenation: This occurs in animal cells when placed in a hypertonic solution, causing them to shrink and form irregular shapes due to the loss of water.Turgidity: This refers to the stiffness and rigidity in plant cells caused by the absorption of fluid, making the cell turgid.Flaccidity: This describes a state where plant cells lose water, leading to decreased pressure on the cell wall and resulting in a droopy, floppy cell structure.which of the following technological advancements was necessary before scientists could study samples from the surface of the moon
