In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?
Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.
PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.
The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.

ANSWER:
Explanation:
The Aquarius Personality: The Water Bearer (Jan 22 – Feb 21)
The personality of an Aquarius is characterized by the need for self-expression, creativity, and a sense of purpose. Aquarians have a natural curiosity about many things and are more than willing to use their far-reaching imaginations to feed that curiosity. Friends or colleagues of an Aquarius may find these unpredictable individuals to be warm and affectionate, though sometimes solitary, relentless in their pursuit of knowledge, and deeply inquisitive.
What Are the Best Career Paths for an Aquarius?
Although Aquarians are highly capable of many things, they are best suited for roles that require unconventional thinking. Aquarians embody many professional strengths, including critical thinking, social consciousness, and assertiveness.
However, the Aquarian personality has its drawbacks like other zodiacs. An Aquarius can lack focus, express apathy toward tasks that diverge from their interests, and insist on getting their way, even when that may not be beneficial for completing the task at hand. These qualities can cloud the Aquarian’s better judgment and stunt their professional growth.
However, positive Aquarian traits aid in professions in service, politics, and fine arts. These career paths allow the Aquarius to flourish in ways that are comfortable for them while encouraging them to amplify the best aspects of their personalities.
What Are Aquarians Like in the Workplace?
An Aquarius will feel at home in work environments that welcome the deep, abstract thought process that is natural to them, such as laboratories and museums. In these work environments, the Aquarius can jump at the chance of aiding a colleague or lightening the load of a manager; they naturally enjoy being helpful to others.
While their thoughtfulness and instinct to help can be great assets in the workplace, Aquarians also have some tendencies which create challenges in the workplace. Aquarians tend towards self-isolation. An Aquarius should remember that not everyone works this way, and that their colleagues will still be expecting communication from them. Disconnecting without notice can make an Aquarius a difficult coworker. Aquarians should inform their colleagues or managers about their desire for occasional solitary tasks during the workweek and explain how it improves their work, being both truthful and proactive in their attempt to overcome the challenge.
Along similar lines, another challenge that Aquarians are likely to face at work is having to adhere to a schedule instead of doing as they please when they please. Aquarians can become irritable when they cannot do what they want, and as we all know, work often includes doing things that are not aligned with things we like to do. Unfortunately, there is no magic fix for this, and Aquarians will have to learn how to fulfill work obligations that include fun and not-so-fun duties. Aquarians can overcome this workplace challenge by redefining what happiness looks like for them at work. The Aquarian may not find joy in fulfilling a task that they do not want to do, but may instead find happiness in getting the work hours they want (to schedule more of what they want to do in their personal time). If the Aquarius can learn to reciprocate what they want at work, they are likely to find greater enjoyment in their professional experiences.

how does the ear function as a sense of "sight" for the blind?
Answer:
Neural scanning shows that even when only abstract sounds are used, the brain engages the visual cortex to build up an audio image. By learning the audio language, users can make their way around obstacles or identify and grasp nearby items.
The ear is not commonly thought of as a sense of "sight" for the blind, but some assistive technologies do use auditory cues to help people with vision impairments navigate and understand their environment.
What is echolocation?Echolocation is the ability of certain animals, such as bats, dolphins, and certain species of birds, to locate objects and navigate through their environment by producing sounds and listening to the echoes that are reflected back. These animals emit high-pitched sounds, such as clicks or whistles, and then use the echoes of these sounds to determine the distance, direction, and shape of objects around them.
The ability to echolocate is made possible by specialized structures in the animals' ears and brains that are able to detect, process, and analyze the echoes. In bats, for example, the larynx is modified to produce a variety of calls, while the ears are highly sensitive and specialized to pick up the echoes of these calls. Similarly, dolphins have a complex system of air spaces in their head, which they use to emit and detect sounds, as well as specialized neurons in their brain that can process the information gathered by echolocation.
Echolocation is an incredibly sophisticated and efficient system, allowing animals to navigate in complete darkness and through complex environments, and to locate and track prey even in the open ocean or in the dark.

Hanan ate a meal that consisted of rice, dal, fish and fried potatoes. Explain the process of digestion of the food with reference to the parts and enzymes involved in the digestive system.
Answer: A digestive system can be defined as a system which is made up of the alimentary canal and the associated glands and organs which produce some of the enzyme- rich secretions that bring about digestion. The process of digestion of food Hanan are, is discussed below.
Explanation:
The food taken by Hanan consist of carbohydrates (rice, potatoes ), protein( fish, dal) , fats and oil( fish, fried potatoes). The digestion of the food taken passess through a long tube ( alimentary canal) which stretches from the mouth through oesophagus to stomach, intestines and down to the anus.
In the MOUTH, the following occurs:
--> The food is cut and grinded into smaller pieces by the help of the teeth.
--> the enzyme ptyalin acts on the carbohydrate part of the food converting it to complex sugar.
--> the food is mixed with saliva, with the help of the tongue, is rolled into a bolus which is then swallowed.
At the STOMACH, food enters through the peristaltic movements of the oesophagus, The following occurs:
--> The muscular walls of the stomach contract and relax forcefully, thus churning the food.
--> Gastric juice( consists of pepsin, renin and dilute hydrochloric acid). Dilute hydrochloric acid activates pepsinogen to pepsin which digests proteins to polypeptides.
--> Food remains in the stomach for three to four hours. By this time, it is a thick, creamy fluid called chyme which them moves to the duodenum (small intestine).
At the SMALL INTESTINE, digestion occurs at the first part called the duodenum, and later part called the ILEUM.
--> Several substances are secreted into the duodenum from the pancreas( pancreatic juice) and liver( bile), the accessory organs of digestion.
--> pancreatic juice contains three important enzymes whose activities include:
• Amylopsin: Breaks down complex sugar to maltose
• Trypsin: breaks down protein into peptides
• Lipase: Breaks down fat into carboxylic acids and glycerol (end product of digestion of fat).
--> Bile from the liver, adds water to the chyme, emulsifies fat and neutralise the action of dilute hydrochloric.
At the ILEUM, intestinal juice is produced by special cells of the small intestine. Their actions include:
• maltase: this acts on maltose converting it to glucose( which is the end product of carbohydrate digestion).
• erepsin: This acts on peptides converting it to amino acids( which is the end product of protein digestion).
Absorption takes place at the small intestine.

Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings are expected to be heterozygous for both traits?
Answer:
The correct answer would be - 25%.
Explanation:
It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.
BbTt is a heterozygous condition and a cross with itself will produce :
Gametes: BT Bt bT and bt
BT Bt bT bt
BT BBTT BBTt BbTT BbTt
Bt BBTt BBtt BbTt Bbtt
bT BbTT BbTt bbTT bbTt
bt BbTt Bbtt bbTt bbtt
Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%

The cactus has a specialized fleshy stem that is specialized to store water for long periods of time. Which plant tissue most likely makes this action possible?
I know the answer is Ground, but i need to know WHY the answer is ground tissue. I WILL MARK BRAINLIEST
(on EDGE)
Answer:
If I were to guess its probably Vascular
Explanation:
Cactuses can store water nearly four months mainly in the winter and watering is not required for them frequently during that time. The stem acts as a reservoir for the amount of water it holds. The ground tissue of cactus has lots of parenchymal cells that store water.
What is parenchyma?The ground tissue system comes from a ground meristem which has three tissues, namely parenchyma, collenchyma, and sclerenchyma.
The ground tissue of cactus has many parenchyma cells that store water.
Thus, it can be concluded that the ground tissues helps cactus to store water for a long time.
