Answer:
The correct answer is - It shows that an RNA probe is necessary to get a signal.
Explanation:
A probe is a specific single-stranded sequence of DNA or RNA that recognizes its complementary sequence in a particular sample genome for synthesis. The RNA probe is placed into close contact with the given sample under a specific environment that allows the RNA probe sequence to hybridize with its complementary sequence.
In this case, square a is the condition where no RNA probe is persent whereas all three other conditions have some sort of RNA probe, however, in C there is no Gene X probe but their probe present. To get a signal in hybridization RNA probe is required and that can be used as control as it can be used to compare if a signal is received or not.
State how a gas produced by photosynthesis is recycled in nature
Answer:
Oxygen cycle, oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide.
Explanation:
In like manner, carbon dioxide passes from blood to the alveoli and exhaled after.
Earth's atmosphere is made of different gases that can affect the Earth's Climate in different ways
True/False
Explain in full details.
Answer:
True. The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere.
The statement is true.
Effect of atmosphere on climateAtmosphere of earth contains oxygen which we use for breathing. The gases present in the atmosphere such as ozone protects us from harmful ultraviolet solar radiation.
It creates the pressure without which liquid water couldn't exist on our planet's surface. The greenhouse gases warms our planet and keeps temperatures habitable for our living Earth.

What adaptations do desert animals have that help them survive the hot dry desert?
Answer:
animals also have to cope i the desert, using adaptations such as being nocturnal or living under ground to survive. camels often live in deserts that are hot and dry during the day, coping with wind-blown sand and cold at night. slit-like nostrils and two rowa of eyelashes to help keep the sand out of their eyes.
Ecologists are interested in quantifying different kinds of biodiversity. In below study outlined here, which kind of biodiversity are ecologists studying?
Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.
a. Genetic diversity
b. Functional diversity
c. Ecosystem diversity
d. Species diversity
Answer:
d. Species diversity
Explanation:
The species diversity can be measured by:
Species richness: Refers to the number of species are inhabiting a defined area. Species abundance: Describe the distribution of the species abundance.Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
Please explain how shade-adapted plants tend to differ from sun-adapted plants, using the terms: specific leaf area, dark respiration, root mass fraction, leaf lifespan.
Answer:
Thickness and number of chlorophyll.
Explanation:
Shade-adapted plants differ from sun-adapted plants due to many characteristics such as thickness and number of chlorophyll. Sun leaves are more in thickness than shade leaves because they develop longer palisade cells. Shade leaves generally have more chlorophyll as compared to sun-adapted plants. Specific leaf area and root mass fraction of Shade-adapted plants are higher as compared sun-adapted plants due to large number of chlorophyll to harvest more sunlight for photosynthesis. Dark respiration is higher in sun-adapted plants when there is darkness as compared to shade-adapted plants which produce food in no direct sunlight.

All of these children (including the fraternal twin sisters in the front row)
are the biological children of the two parents in the middle of the picture.
Based on everything that you have learned in this unit, explain why these
brothers and sisters do not look exactly alike. Include the processes of cell
division and the rules of genetics in your answer.
Answer:
Explanation:
Because in the fetus stages of fraternal twins two different eggs get fertilized. Therefore, genetics won't be the same for both twins. But if they were identical twins the fertilized egg was to divide and the two zygotes would've carried the same genetics of each other.

What does the flagella do in a euglenoid?
Answer:
Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir.
The budding of clathrin-coated vesicles from eukaryotic plasma membrane fragments can be observed when adaptations, clathrin, and dynamin-GTP are added to the membrane preparation. What would you observe if you omitted (A) adaptations, (B) clathrin, or (C) dynamin
Answer:
Explanation:
Adaptins:
Adaptor proteins, which attach the clathrin to the membrane, are required for clathrin-coated vesicles to form. Clathrin cages form in solution at strong clathrin concentrations and under the right ionic environments and parameters, but they are empty hollow shells without membranes or other proteins. The data for clathrin baskets are included in the clathrin molecules themselves, as shown by the self-assembly of clathrin into baskets. Clathrin coat cannot form or build up without adjusting to the membrane it is attached to.
Clathrin:
Adaptins bind and act synergistically to specific receptors without clathrin, but no vesicles or clathrin are formed. There exists coated pits formations, but no clathrin coat.
Dynamin:
Clathrin-coated pits can develop and progress toward vesicle formation in the exclusion of dynamin, but the final step, known as membrane fusion, is inhibited. Consequently, in the exclusion of dynamin, strongly invaginated covered pits will be noticed. As a result, vesicles are unable to pinch the membrane.
Suppose plasma membrane fragments were prokaryotic cells, there would be no endocytosis and hence no adaptin or coatings. Endocytosis is not performed by prokaryotic cells. There are no receptors with adequate cytosolic tails in a prokaryotic cell that might facilitate the binding to adaptor proteins. As a result. no clathrin-coated vesicles will develop.

Alleles are described as ____________________. homologous chromosomes homologous chromosomes alternate versions of a gene alternate versions of a gene alternate phenotypes alternate phenotypes environmental factors that affect gene expression
Answer:
The correct answer is - alternate versions of a gene.
Explanation:
In a cell, if there are two copies of each chromosome, these are called homologous chromosomes, one come from the father and the other comes from the mother, which helps in promoting the variety and stability of a species.
Different or alternate versions of genes are possible that can result in two phenotypes for the same trait, these alternate versions called alleles. Alleles can be dominant and recessive.

5 The systolic blood pressure reading of 140-159 the systolic blood pressure reading of 140 - 159 is what stage of Hypertension?
A Stage 2
B Stage 1
C Stage 3
D High Normal
Answer:
B. Stage 1
Explanation:
Systolic blood pressure is less than 120 mm Hg and Diastolic less than 80 mm Hg so it is considered as normal. Pre-Hypertension occurs when the Systolic blood pressure is 120 - 139 and Diastolic pressure is 80 - 89. Stage 1 Hypertension is considered when the Systolic blood pressure is 140 - 159 and Diastolic blood pressure is 90- 99. If the Systolic blood pressure is greater than 160 it is considered as Stage 2 Hypertension.
