Do you have siblings? You may have similar traits, but you are also very different. We exhibit genetic variation, even in the sa

me family, thanks to sexual reproduction. During sexual reproduction gametes are produced through the process of meiosis. Gametes, egg or sperm, are haploid cells. The 46 chromosomes our body cells contain are reduced so when egg or sperm are produced, there are 23 chromosomes each. In any family, with the same parents, those 23 chromosomes vary every time a gamete is produced, except in the case of identical twins. Look at the diagram of meiosis. When the process is complete, each haploid gamete contains a variation of the original diploid cell. During meiosis chromosomes move randomly to separate poles. A human gamete will end up with 23 chromosomes after meiosis, but ________________ assures that each gamete will have one of many different combinations of chromosomes. A) law of dominance B) meiotic divisions C) reduction division D) independent assortment

What are the four criteria for life?
zavuch27 [327]
Planet earth is the only known region of the universe to host life and so the basic criteria for life is based on observations made here. For an entity to be considered a living organism it must contain DNA or some other means of storing genetic information. The second criteria is that it must have some way of extracting nutrients from its surroundings. The organism must be able to respond to environmental stimulus and last but not least it must be able to reproduce.

You place an inoculum of your bacterium on a glass slide and add a drop of hydrogen peroxide reagent. Promptly you see bubbles a
marissa [1.9K]

Answer:

The correct answer is A) Biochemical test

Explanation:

In microbiology biochemical test is used to examine the metabolic activities performed by bacteria to identify that microorganism. So in biochemical test enzymatic reaction of cell is usually investigated because there is difference in enzymatic activity of different species of bacteria.

For example, catalase test that is used to differentiate between catalase-positive and catalase-negative bacteria is an example of biochemical test. Catalase-positive bacteria have the catalase enzyme that breaks hydrogen peroxide into water and oxygen which is confirmed by bubbles that appear on glass slide.

Catalase negative bacteria do not form bubbles when they are put in hydrogen peroxide which shows that they lack catalase enzyme. So the right answer is A.

he burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and other
Arturiano [62]

Hey there!

A Burrowing owl's habitat is destroyed which is due to human activities and will come under Artificial destruction via human influence and not due to a natural destruction like cyclones, High Richter scale earthquakes, hurricanes with extremely high knot speeds, etc. Instead I'll say because of which the population of the burrowing owl will obviously decrease because they're more adapted to "their previous environment" and most likely "wouldn't adapt to a new unfamiliar environment".

To break these contradictions down simply said "they're unaware of the rules, regulations, type of soil, type of trophic levels, number of predatory organisms, etc. this makes it pretty hard to move from their once said naturally provided nature-made habitat to the burrowing owl, which got lost due to habitat annihilation by human cause. Further making the owls to adapt and change their "NATURAL TRAITS" to make it "CUSTOM" because of which these aren't going to help them instead they'd go either extinct by moving to a newly known unfamiliar habitat rather than their naturally nature gifted habitation.

So Yeah, the correct option [after the question mark ends] to be the least likely outcome would've been  "the population of species of burrowing owl maybe increase as per arriving in a new habitat or introduced to newly made surroundings". This is "Highly and the most unlikely" or the "least likely predictable outcome" for burrowing owls. Introduction of species to newer habitats without any prior training, kills the species and it's progenies.

Hope this helps  you and gives you the detailed analysis for this query for burrowing owls!!!!

Which of the following statements about ATP-powered pumps is NOT true? All ATP-powered pumps contain at least one transmembrane
MAVERICK [17]

Answer:

Only P-, F-, and V-class pumps transport ions.

Explanation:

The distinct classes of ATPases include:

1) Only the P-type ATPase actively transports ions across biological membranes. P-ATPases (also named E1-E2 ATPases) are found both in plasma and organelle membranes. These ATPases serve to transport ions and phospholipids by hydrolyzing ATP to ADP and phosphate.

2) A- and F-ATPases synthesize ATP by transforming the energy from a gradient of ions across the cell membrane.

3) V-ATPase (also known as Vacuolar-H+ ATPases) acidifies vacuole, lysosome, endosome and Golgi membranes. This type of ATPase couples the hydrolysis of ATP to the active transport of protons across biological membranes.

4) E-ATPases hydrolyze extracellular ATP.
