Answer:
Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction.
In an organism of genotype Aa, half the reproductive cells carry 'A' and half carry 'a'. Mendel called this
Answer:
The correct answer is - Segregation
Explanation:
An organism with the genotype Aa whose half of the reproductive cell or gametes carry A and the rest of the gametes or reproductive cell carries allele a. According to the laws of Mendel, it is the law of Segregation.
In a diploid organism, the genotype of an individual possesses a pair of alleles (50-50 %) for any particular character and is passed one of each to next-generation from each parent.
Read the section "Seeds." Which sentence from the section states the main idea about seeds? A The life cycle of flowering plants begins with a seed. B The outside of a seed is called a shell. C The wind blows some, and others float on water. D The next phase starts when a seed gets someplace it can start growing.
Answer:
A The life cycle of flowering plants begins with a seed.
Explanation:
Seeds are structures found only in a group of plants called higher plants, comprising of gymnosperms and angiosperms. Seeds are the developed/fertilized ovules of a plant.
Seeds are basically the reproductive unit of the angiosperms, also called FLOWERING PLANTS i.e. plants that produce flowers (reproductive structures). This means that the life cycle of flowering plants begins with the germination of the EMBRYO in a SEED.

Among the microbes responsible for producing fermented foods, the two most prominent groups are the lactic acid-producing bacteria and yeasts that produce _________.
Answer:
Alcohol
Explanation:
Fermentation is a type of anaerobic respiration employed by organisms like yeast and certain species of bacteria. As stated in this question, YEAST and the BACTERIA that produces lactic acid as a product are the two major microbes that undergoes this fermentation process.
However, YEAST (a unicellular fungus) undergoes fermentation to yield alcohol and CO2 as its product. Yeast breaks down sugar molecules into ethanol (C2H5OH) and carbon dioxide (CO2) in its cells enabling it to be used in the production of fermented foods like cheese, beer etc.
What is the name of the approach to biological research that integrates data from multiple levels of complexity
Answer:
systems (system biology)
Explanation:
Systems biology can be defined as a methodology whose interest is to understand the high scale levels of complexity in biology (i.e. organism level, tissue level, cell function, etc) by integrating information/data from different sources, and thus examine the interaction between biological components. This approach is contrary to reductionism, which is another approach used in biology research. Therefore, systems biology is a holistic approach aimed at modeling complex biology systems by applying computational and mathematical methods, enabling to understand biological systems.
Fuel wood is particularly important in many developing countries, which leads to deforestation and overuse of many species trees. Brainstorm two ideas that could help to reduce fuel wood demand, and explain how your ideas would contribute to sustainability of forest resources.
Answer:
My ideas are the following:
1. Maintain clean cardboard and paper discards to be subsequently recycled
2. Reforest the degraded areas using native species with rapid generation times to be subsequently reutilized
Explanation:
In the home it is possible to sort waste materials, including cardboard and paper. These waste products are made of 100 % recyclable materials but only when they are clean. For efficient recycling purposes, it is therefore necessary to maintain clean both materials (for example, by removing plastics or other materials attached to cardboard and paper). Moreover, reforestation can be a sustainable and cost-effective method for protecting native trees in developing countries. In these countries, economic issues may hamper the adoption of reforestation techniques, thereby new areas may be deforested to obtain more fuelwood. To solve this problem, it is possible to reforest vast areas by using native trees that exhibit rapid generation times, which may then be used as an alternative source of sustained raw material.

Could emigration or immigration have played a major role in determining the size of the reindeer
population? Explain. Think about where these reindeer were and whether they could swim that far
Answer:
Yes.
Explanation:
Yes, emigration or immigration have played a major role in determining the size of the reindeer population in specific area because immigration is done by the animals in search of food. The animals moves from one region to another in search of food so due to this movement the population of reindeer decreases in that specific area. Reindeer are good swimmers so due to this ability they cross the vast Yukon River which is half mile wide.

D) pulmonary trunk.
please help and define the difference in pulmonary circuit and pulmonary circulation. thanks
Pulmonary trunk does not belong to pulmonary circuit.
What is pulmonary circuit?The circulation provides oxygen and blood to all the parts of the body. The circulation is of two types pulmonary circulation and systemic circulation. When blood moves from heart to other organs it is called systemic circulation.
When blood moves from heart to lungs is called pulmonary circulation. The circulation involves four chambers such as left atrium, left ventricle, right atrium and right ventricle.
Pulmonary trunk is not a part of pulmonary circuit. Blood will flow from auricles to ventricles.
Therefore, Pulmonary trunk does not belong to pulmonary circuit.

What organelles are associated with carbohydrates?
Answer:
The only organelle that is associated with carbohydrate synthesis is the Golgi Apparatus.
Explanation:
Hope this helps!
The organelles which are associated with carbohydrates are mitochondria and the endoplasmic reticulum (SER).
What are Mitochondria?Mitochondria may be defined as the double-membrane bound cell organelle which is found in the cytoplasm of the cell. It was first recognized by Kolliker in muscle cells of insects in 1880.
Mitochondria are known as the "Powerhouse of the cell". This is because the energy required for various activities is released by mitochondria in the form of ATP. This organelle also oxidizes the pyruvic acid and forms energy in the form of ATP.
The smooth endoplasmic reticulum is directly associated with carbohydrate metabolism along with other metabolic processes like the synthesis of lipids, detoxification, etc.
Therefore, mitochondria and the endoplasmic reticulum (SER) are the organelles that are associated with carbohydrates.

What type of photoreceptor cell allows us to see gray tones in dim light, and provides our peripheral vision
Answer:
Rods.
Explanation:
There are two types of photoreceptor cells, the cones, and the rods.
The cones adapt our vision to bright light and allow us to see colors. On the other hand, rods photoreceptors make us see in the dark and do not perceive many colors; that is why we can not distinguish colors in the dark. Also, they provide peripheral vision since they are on the external edges of the retina.
Besides controlling what goes in and out of the cell, what other two jobs does the cell membrane have?
Answer:
It protects the cell by acting as a barrier.
receives chemical messengers from other cell.
Explanation:
Cell membrane act as a barrier which keep harmful substances to enter the cell and prevents substances to go out of the cell. It also receives chemical messengers and signals from other cell. This cell membrane is responsible for controlling of the flow of substances in and out of the cell. It also helps the cell in cell mobility from one place to another.
