Answer:
The correct option is white.
Explanation:
As the options are not given, the options are found online and are as follows;
(a.) green (b.) white (c.) colonies will not grow (d.) blue (e.) clear
Out of this, white is the true option because in recombinant plasmid lac Z gene is disturbed and cannot produce beta galactosidase enzyme and there is no hydrolysis of x gal and no blue so recombinant plasmid gives white colonies)
Complete the statement about genetic variation.
Meiosis contributes to genetic variability when
the chromosomes line up randomly during
metaphase 1 anaphase I prophase I. This
random line-up means that when the cell divides,
the number of chromosomes in each cell is the
same, but the contents are not. This process is
called | independent assortment |gene linkage |
crossing over|. During meiosis, |gene linkage|
|independent assortment | crossing over | increases
genetic variation because it shuffles portions of
chromosomes around.
Answer:
1. Metaphase 1
2. Independent assortment
3. Crossing over
Explanation:
Meiosis is a kind of cell division that reduces the chromosome number of the parent cell by half. It only occurs during sexual reproduction and ensures genetic variation in sexually reproducing organisms.
Meiosis contributes to genetic variability when the chromosomes line up randomly at the cell plate during METAPHASE 1 of meiosis. This process of random alignment is called INDEPENDENT ASSORTMENT of genes. Generally, meiosis is able to ensure genetic variability due to a process called CROSSING OVER. Crossing over is a process whereby nonsister chromatids of homologous chromosomes exchanges/shuffles genetic contents.

Grasses → mice → cat → coyote A natural disaster of a fire has occurred what could happen to this food chain? The grasses will be gone and all of the consumers will be able to leave. The grasses will be gone and some of the mice will die but the number of cats and coyotes will remain the same. The grasses will be gone but the number of consumers will all stay the same. The grasses will be gone and any surviving consumers will have to look for new resources in that environment. Nothing will happen to this food chain.
Answer:
The grasses will be gone and any surviving consumers will have to look for new resources in that environment.
Explanation:
The fire will destroy the grass and harm some of the consumers. Without grass, the mice population will drop and that will cause the cat population to drop and that will lead to the coyote population to also decline. The remaining consumers will have to move to find further resources to survive.

Undersea vents called black smokers release superheated, mineral-rich water. Light does not penetrate the water, making photosynthesis impossible. However, diverse communities of organisms exist around black smokers at depths of 2100 m below the ocean surface.
Which is the most likely reason these diverse communities can exist so deep in the ocean?
Group of answer choices
Black smokers are warm like tropical land areas.
Black smokers produce sulfur that blocks light and creates a good hideaway for many organisms.
Dead organisms that serve as bacterial food sources drift down from water close to the surface.
Producer organisms use minerals in the water to make food through chemosynthesis.
Answer: Producer organisms use minerals in the water to make food through chemosynthesis.
Explanation:
The producer organisms that exist around these underwater vents are able to produce food through an alternative process to photosynthesis known as Chemosynthesis.
With Chemosynthesis, producer organisms use the minerals in the water from black smokers by converting molecules that contain carbon to organic matter by using energy they acquired from oxidizing ferrous ions and other inorganic compounds.

The fossil record indicates that in some cases reasonably well-defined species appear suddenly and remain unchanged for a long time before they become extinct. This phenomenon is referred to as
Answer:
The correct answer is - punctuated equilibrium.
Explanation:
The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.
This phenomenon suggests that once it made in the fossil record the population becomes stable for a long time until they become extinct and have to adapt to the changes take place to survive.
4) What factors influence the circulation of the Earth's atmosphere,
thereby producing our weather?
The uneven heating of the earth's surface is one of the main variables affecting the circulation of the atmosphere globally along with seasonal variations in precipitation and temperature and Earth turning on its axis.
What is weather?The state of the atmosphere is referred to as the weather, and can be described in a number of different ways, including the degree to which it is hot or cold, wet or dry, quiet or stormy, clear or cloudy. The troposphere, the lowest layer of the Earth's atmosphere, is where the majority of meteorological events take place. The stratosphere is the next layer up from the troposphere. The term "weather" is used to describe the temperature, precipitation, and other characteristics of the atmosphere on a day-to-day basis.
Variations in air pressure, temperature, and moisture from one location to another are the primary contributors to a day's weather. These disparities can be attributed to the fact that the angle at which the Sun is positioned at any given location varies with latitude. The vast temperature difference between the polar and tropical air masses is what gives rise to the biggest scale atmospheric circulations.

Which influence has immigration and migration had on the population of Texas?
A.) It has kept the growth rate of Texas the same as the growth rate of the United
States.
B.) It lowered the amount of cultural and economic activity in Texas.
C.) It contributed to the 38% of Hispanic Texans as of 2010.
D.) It decreases the need for public services in rural communities.
Answer:
The answer is choice C.
Explanation:
In this question, I will use the following format: two d*mbs, a trick, & a true. In this strategy, there are two d*mb answers, one answer made to trick the reader, and one true answer (which is the correct answer).
The two d*mbs of this problem are choices B and D. B simply makes no sense since immigration and migration would increase the amount of cultural and economic activity in Texas if anything. I feel as though D is illogical because it is more likely that immigration and migration would increase the need for public services in rural communities. Due to B and D being the opposite of what is necessary for the answers to be true, they can both be swiftly eliminated.
A is the trick of this question. Although it may seem valid at first, there is a fatal flaw about it: the fact that Texas is within the United States. Texas, despite its size and population, is one singular part of the US. It is impossible for Texas to be the only part of the United States to grow. As a result, the growth rate of Texas can never be the same as the growth rate of the United States.
C is the true in this problem. Immigration and migration contributing to the 38% of Hispanic Texans (as of 2010) is indeed a logical answer that adds up. Additionally, when looking at the official resources that this question is derived from, the text clearly states that 'The numbers and percentages of Hispanics in Texas grew greatly between 2000 and 2010. About 2.8 million more Texans identified themselves as Hispanic in 2010 compared to 2000. Hispanics represented 38 percent of all Texans compared to about 32 percent in 2000.' While this information may not seem all that important at a first glance, it actually supports this answer quite a bit. The text clearly provides valid proof of answer choice C; it gives the cause of answer choice C quite plainly and undeniably.
This means that A is the trick, B and D are the d*mbs, and C is the true. Due to the evidence and verification previously stated in my answers, it is quite clear (to me) that the answer is indeed choice C.

A tall pea plant results from a dominant tall allele while the short phenotype results from two recessive alleles. What is the frequency of short offspring (pp) when a tall pea plant with one tall allele (Pp) is cross-pollinated with a short pea plant (pp)?
Answer:
0.5
Explanation:
Took the test xd ♡
The probability of short pea plant when a heterozygous parent cross with recessive is 0.5.
Law of dominance:
The cross between two pure parents results in the heterozygous dominant offspring in the first generation.
Here,
Parents are
P- dominant tall
p - recessive
Pp x pp
The cross,
p p
P Pp Pp
p pp pp
From the cross it is clear that 50% of the offspring will have recessive alleles.
Therefore, the probability of short pea plant when a heterozygous parent cross with recessive is 0.5.
