Basal ganglia collaborates with the frontal lobe and brain stem to organize movement and behavior, and the cerebellum, which is engaged in the coordination of motor movements, is used by zombies.

The cerebellum and basal ganglia, areas of the brain that regulate balance and fluid motion, have been proposed as potential culprits for the clumsiness of the zombies. They may be stumbling awkwardly towards their objective as a result of damage to these areas.

Zombies are incapable of making complex judgements because the virus eats away at the frontal lobes of the brain, which are involved in problem-solving. They are also unable to walk well due to cerebellar dysfunction. Additionally, these humanoids have an odd preference for consuming human flesh.

Grey matter is a part of the central nervous system that is found on the surface of the brain.

It is a neural tissues that has alot of cell bodies of neurons, neuroglia and contain more unmyelinated axons and surronds the narrow central canal.it is distinguished from white matter because it has alot of cell bodies and unmyelinated axons and also it is not as white as white matter with greyish color.

Grey matter form spinal tracts which are the pathways where signals are sent from the brain to all part of the body.

A grower who wishes to enhance plant growth by adjusting the carbon dioxide levels in the greenhouse will use a NDIR as analyzer to evaluate carbon dioxide levels.

Carbon dioxide can be measured using infrared detectors, also known as NDIR analyzers, because it is an excellent absorber of infrared energy. Depending on the application, carbon dioxide can be measured in percent (%) or parts per million (ppm).

A sensor is used to measure carbon dioxide. The NDIR non-dispersive infrared sensor is one of the most common.

Its popularity stems from its long life-span, high speed, and low cross-sensitivity to other gases. An NDIR CO2 sensor detects infrared light in an air sample.

Thus, NDIR can be used.

Answer:

Anaphase

Explanation:

The motor also known as efferent division of the nervous system consists of motor nerves which ends in the skeletal muscles. These nerves provide signals from the CNS and PNS to the glands, muscles, and organs, which affect how those tissues function. These neurons are responsible for relaying CNS impulses to the viscera, muscles, and glands.

According to biology's traditional idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals to and from various regions of the body. The nervous system notices bodily impacting environmental changes, and then collaborates with the endocrine system to react to such occurrences. Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue. The discovery of electrical signals in plants and their utilization in recent decades, however, has called into question this conventional wisdom. These findings have led some researchers to suggest that plants have nervous systems and that the field of plant neurobiology should be established.

True. The accumulation of greenhouse gases in the Earth's atmosphere, which leads to global warming, is primarily caused by human activities such as the burning of fossil fuels, deforestation, and industrial processes that release carbon dioxide, methane, and other gases into the atmosphere.

These gases trap heat in the Earth's atmosphere, leading to a rise in global temperatures, changes in weather patterns, and other impacts on the environment and human societies. While some greenhouse gases occur naturally in the atmosphere, the current rate and scale of their accumulation are largely due to human activities.

No, starch is not structural component in plants, rather it is a energy storage unit, which helps the plants to grow and produce food and also provide energy for other vital functions.

The structural component in plants is cellulose, which is found only in plant cells in the cell wall. Since it is stronger in nature, so it helps in maintaining shape of the cells and therefore plants as a whole. Starch on the other hand is a polysaccharide, which is made up of number of monomer units of glucose. These polymeric units are bound together by covalent bonds. When the metabolism of monomer units take place, this provides ATP (Adenosine Triphosphate) molecules. Hence, these starch molecules provides energy to cells.

Answer: I guess the first one

Explanation:

The construction of the energy plant will likely pollute the water flowing in front of it on the riverbank.

The fact that the energy plant will use the water from the river for cooling means that the water will be exposed to thermal pollution. The increase in the temperature of the water will cause less dissolution of oxygen in the water.

As dissolved oxygen levels drop, the aquatic organisms in the river will become negatively affected due to the resulting oxygen stress and they may begin to die.

Vitamin B1, or thiamin, is the most susceptible nutrient to destruction when foods are preserved with sulfites. The sulfites can cause a chemical reaction that breaks down the thiamin in the food, which ultimately reduces the vitamin content.

Sulfites are commonly used as preservatives in foods because they can help delay the growth of bacteria and molds. Some food items commonly preserved with sulfites include dried fruits, jams, pickles, wine, and processed potatoes. While foods preserved with sulfites are still able to provide essential nutrients, thiamin should be increased in the diet to make up for the loss of nutrients caused by the sulfites.

Eating complex carbohydrates, such as whole grains, can be beneficial for increasing thiamin in the diet, as well as vitamin-rich food items such as eggs, legumes, nuts, and leafy green vegetables. Supplements may also be useful if the diet does not provide adequate thiamin levels.

Overall, when consuming foods that are preserved with sulfites, it is important to be aware of the potential loss of vitamins and minerals, and to strive for a diet that is rich in essential nutrients.

Answer:

4. had certain inheritable traits that made them to survive

Explanation:

The options are:

1. produced offspring that all had identical inheritable characteristics

2. Did not face a struggle for survival

3. learned to migrate to a new environment

4. had certain inheritable traits that made them to survive

The correct option would be option 4.

This is law of natural selection at play. According to this law, organisms that are better suited to an environment survive, multiply, and pass their survival genes to their offspring. Those that are weakly adapted to the environment usually fade off the environment gradually.

Hence, other species of mammals exist today most likely because they had inheritable traits that made them to survive the changing environment while mammoths became extinct because they were poorly adapted to changing environment.

Carbon is one of the elements that are involved in the biogeochemical cycle.

One way carbon moves from the atmosphere to the biosphere is through a process by which plants use light energy and convert it into biochemical energy. This process is called photosynthesis. Plants use energy from the sun to combine carbon dioxide and water to form glucose.

In photosynthesis, six molecules of carbon dioxide react with six molecules of water to produce oxygen and glucose as follows;

6CO2 + 6H2O ---->C6H12O6 + 6O2. The products of photosynthesis are glucose and oxygen.

Carbon is incorporated  into the carbon cycle via water in the hydrosphere when carbon dioxide dissolves into oceans as the bicarbonate ion. The oceans serve as the largest reservoir of carbon. About 37,000 billion tons of carbon are stored in the oceans out of  about 65,500 billion tons of carbon available globally.

Proteins, nucleic acids, lipids, and carbohydrates are based on carbon. Carbon is contained in all biological molecules which makes it very important in biochemistry.

Photosynthesis is a chemical reaction as shown above. It occurs in the chloroplasts of plant cells which is able to trap energy from the sun in order for the process of photosynthesis to take place.

The reservoirs that make up the carbon cycle are four;

Carbon is transferred from the atmosphere to the biosphere by photosynthesis when green plants absorb carbon in order to produce biomass. The overall scale of the carbon cycle is planetary.

The control of microbial growth can be achieved through the use of various techniques. Salted meats, jams, and honey are some examples of the methods that can be used to control microbial growth.

The following is a discussion of these methods:

Salted Meats:Salt is used in meats to limit the growth of bacteria. Meat is treated with salt, which draws out the moisture and reduces the water content, which slows down the growth of bacteria. The bacteria require water to survive, and when the moisture level is reduced, they are unable to survive. salting meats is a common way to preserve them.

Jams:Jams are made from sugar, which is a natural preservative. Sugar reduces the water activity of the jam, making it difficult for bacteria to survive. Bacteria require water to survive, and when the water content is low, the bacteria cannot grow. The sugar content of the jam also helps to create an acidic environment, which is another factor that inhibits bacterial growth.

Honey:Honey is an excellent antimicrobial agent due to its high sugar content, low pH, and the presence of hydrogen peroxide. The high sugar content of honey makes it difficult for bacteria to grow, while the low pH of honey creates an acidic environment that inhibits bacterial growth. Additionally, the hydrogen peroxide in honey is a potent antimicrobial agent that can destroy many types of bacteria.They create unfavorable conditions for the growth of microorganisms.

Explanation:

Phospholipid synthesis does not involve the condensation of CDP-alcohol with diacylglycerol.

Correct option is A.

This reaction would produce a pyrophosphate, which is not necessary for phospholipid synthesis. Instead, phospholipid synthesis relies on the condensation of CDP-diacylglycerol with alcohols or the exchange of free alcohols with head group alcohols of phospholipids.

The condensation of CDP-diacylglycerol with alcohols is achieved by linking the CDP-diacylglycerol through two glycerol substituents, allowing for a single glycerol substituent to be left for attachment to a saccharide or alcohol molecule. The exchange of free alcohols with head group alcohols of phospholipids occurs through the transesterification reaction, which involves breaking the ester bond between a fatty acid and the glycerol backbone.

Amygdala

Explanation:

Generalized anxiety disorder (GAD occurs when an individual experiences excessive and continuous worry and anxiety about certain things ,It is caused by  over activation  of the region of the brain that mediate response to fight and flight stimulus and fear,the amygdala.

Its  symptoms are  difficulty with concentrations, overthinking ,indecision, irregular sleep patterns.

Two brain circuits  transmitted  sensory stimuli of fear or danger in the brain  to two regions of the brain,

1. the peripheral cerebral cortex for voluntary decisions

2. the Amygdala for involuntary emotional decision.

The amygdala  is concerned with  how the body reacts to the effects of the stimuli in the immediate environments, the interactions of the stimuli with  the emotions of the subject, and the involuntary response .

To  respond to the  stimuli of fear. The amygdala stimulates the hypothalamus.The latter activate the cardiovascular and breathing centre .Hence,adrenaline is released into the blood stream.The  increases involuntary response to anxiety,which gives a fast response..The cerebral cortex response takes time to relay response.

Amygdala,  stores memories of all emotions, fear, and anxiety. In patients with  this disorder, the Amygdala is sensitive and had been adapted to the memory   of fear and anxiety stored.Therefore, every slight normal event which should give any danger  is over reacted to  by the amygdala with  fear or flight response, This triggers the two brain circuits  to give anxiety-provoking events.
