Which plant belongs to the cabbage family?
Answer:
Broccoli, cauliflower, Brussels sprouts, kohlrabi, collards and kale. These cool-weather cole crops are members of the cabbage family
Explanation:
Plants like kale, cauliflower, broccoli and collards belongs to the cabbage family.
What is a family?The family is ranked above the genus and below the order in taxonomy. More closely connected to one another than they are to other members of the same order are members of the same taxonomic family.
For instance, the Order Carnivora includes foxes, coyotes, lions, cats, otters, and weasels.
Today's taxonomy system divides families into orders. A taxonomic rank employed in the classification of organisms and acknowledged by the nomenclature codes is the order in biological classification.
The medium-sized and commercially significant family of flowering plants known as the mustards, crucifers, or cabbage family is known scientifically as the Brassicaceae or Cruciferae.
The cabbage family includes plants like kale, cauliflower, broccoli, and collards.
Thus, these are some plants of cabbage family.

How is genetically modified corn produced?The GMO corn Bacillus thuringiensis (Bt) produces proteins that are poisonous to some insect pests but not to humans, pets, or cattle.
The most popular bacteria for GM plants is known as Agrobacterium tumefaciens. The desired gene is introduced into the bacterium, and the bacterial cells then introduce the new DNA into the plant cells' genome. The successfully incorporated plant cells are then cultivated to produce a new plant. This is how genetically modified corn is produced.
Thus, step 3 in the process of developing genetically modified corn is the gene of interest inserted into an expression cassette. Therefore, option B is correct.

A)
Children are more at risk than adults because they take in more air per unit mass than adults.
B)
Adults are most at risk because they have the highest exposure to environmental hazards.
C)
Elderly people are most at risk because their immune systems do not perform efficiently.
D)
Children are least at risk because they have well functioning immune systems.
E)
Adults are most at risk because they take in more pollutants relative to their size than children.
Answer: A)
Explanation:
Children are at a higher risk of suffering negative effects from environmental hazards than adults, because children do not have fully developed immune systems. In addition, children have a higher exposure to environmental hazards, because they spend more time outside, on average, than adults. Children also take in more air per unit mass than adults, which means that they also take in more pollutants relative to their size.

The bacteria Lactobacillus acidophilus are frequently used in the production of yogurt. These bacteria use lactic acid fermentation when oxygen is not available. What would happen to the bacteria under anaerobic conditions if the lactic acid fermentation pathway were blocked?
A.
The bacteria could no longer regenerate the NAD+ needed for glycolysis, so it would stop producing ATP.
B.
The bacteria could switch to using the Kreb's cycle, so it would continue producing ATP.
C.
The bacteria could no longer make the NADH needed for chemiosmosis, so it would stop producing ATP.
D.
The bacteria could switch to using alcohol fermentation, so it would continue producing ATP.
Answer:
A. The bacteria could no longer regenerate the NAD+ needed for glycolysis, so it would stop producing ATP.
Explanation:
According to the given information in this question, Lactobacillus acidophilus is a bacterium species that uses the lactic acid fermentation when there is no oxygen in its cell i.e. under anaerobic conditions. This means that it converts glucose to lactic acid during this anaerobic respiration process.
However, if the lactic acid fermentation pathway were blocked under an anaerobic condition, this means that it will be no longer be able to perform respiration and hence stop production of ATP. This is because the bacteria will no longer regenerate the NAD+ (electron acceptor) needed for glycolysis, so it would stop producing ATP. Note that, all living organisms, whether aerobic or anaerobic, undergo GLYCOLYSIS, which is the first stage of cellular respiration.

survive within the changing environmental limits.
Answer:
living, components can likewise influence an organic entity's capacity to make due in an environment. They incorporate food accessibility, rivalry with different life forms, plant cover accessibility, predation, sickness, parasitism, swarming, territory discontinuity and the presence of human populaces. An absence of trees can influence populaces of birds or other arboreal organic entities, which may depend on tree cover for settling and stowing away from hunters. Some biotic elements influence abiotic factors also, for example, plants that become taller than contending plants and square daylight, or an absence of disintegrating natural matter or nitrogen-fixing microorganisms that prompts low nitrogen levels in the dirt.
15. Describe how the structure of the bird respiratory system provides the energy the
bird needs for flight.
Answer:
The bird's respiratory system consists of paired lungs, which contain static structures with surfaces for gas exchange, and connected air sacs, which expand and contract causing air to move through the static lungs.
Birds do not have a diaphragm; instead, air is moved in and out of the respiratory system through pressure changes in the air sacs. ... Bird lungs do not expand or contract like the lungs of mammals. In mammalian lungs, the exchange of oxygen and carbon dioxide occurs in microscopic sacs in the lungs, called 'alveoli.'
Air sacs are found as tiny sacs off the larger breathing tubes (tracheae) of insects, as extensions of the lungs in birds, and as end organs in the lungs of certain other vertebrates. They serve to increase respiratory efficiency by providing a large surface area for gas exchange.
How do birds respire?
Some birds can sing while they fly! ... When the bird takes a second breath, the air in the lungs is sucked into the cranial air sacs -caudal thoracic, cervical, and clavicular. The cranial air sacs act as a holding chamber which provides a small back flow of air into the lungs during expirations.

Many organisms in the ocean (like plankton) rely on this source of food. What effects do you think this change in the decrease speed of the ocean currents could have on living things on the ocean?
Please help
Answer:
If the speed of ocean currents slows down, some living beings in the ocean would find it difficult to feed and reproduce.
Explanation:
As we already know, ocean currents act as a transport chain that transports hot water to the poles and cold water to the tropics. However, this ability to transport ocean currents also acts in the transport of nutrients and food for living beings that live on the seabed and do not move, but live in a fixed place. They also transport the reproductive cells of these beings to other places in the ocean, being important in the reproduction of marine life. If the speed of ocean currents decreases, the feeding and reproduction of some marine life organisms will be impaired.
(b) Describe the characteristics of the interior of the aquaporin channel protein that allow water to flow through AND exclude glucose.
If isolated keratinocytes are placed in a hypotonic solution for 24 hours, explain the net direction of water movement AND why the
rate of water movement slows down over time.
Answer:
Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices.
Explanation:
Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices. These aquaporin protein have different size of water channels that allow water through to pass through it but it does not allow glucose to move through it due to its large size. The direction of water movement is toward the cell because there is low water inside the cell as compared to outside environment so the water moves inside the cell and rate of water movement slows down over time due to filling of empty spaces with water.
explain why biodiversity in an ecosystem is important?
Answer:
It is important because we need many different types of animals. Food chains are made up of many different links, and if there are fewer links, this will lead to animals not being able to feed.
