Answer:
The cryosphere is the portion of the Earth's surface where water is in solid form. It thus includes sea ice, lake ice and river-ice, snow cover, glaciers, ice caps and ice sheets, and frozen ground. The snow cover has the largest extent, with a maximum area of more than 45 106 km2 (Table 1.1). Because of the present distribution of continents, land surfaces at high latitudes are much larger in the Northern Hemisphere than in the Southern Hemisphere. As a consequence, the large majority of the snow cover is located in the Northern Hemisphere (Figs. 1.15 and 1.16). The same is true for the freshwater ice that forms on rivers and lakes in winter. Both the snow cover and freshwater ice have a very strong seasonal cycle, as they nearly disappear in summer in both hemispheres (Table 1.1).

Answer:
Options A , C , E
Hope it helps!!
Smooth muscle is one of the three types of muscles involved in controlling the movements inside your body organs and is involuntary. Thus, options a and e are correct.
What are smooth muscles?Smooth muscles are the non-striated muscle that lacks sarcomeres and striations and thus lacks bands. They are found through the internal body structures and have a variety of functions.
The smooth muscles can be found in the walls of the liver, intestines, pancreas, urinary tract, uterus, etc. but not in the heart. They also have a spindle shape that contains only one nucleus in it.
They are not under the control of the organisms and rather are controlled by the nervous system, skeletal system, chemicals, and hormones.
Therefore, the smooth muscles are involuntary muscles that control the internal structure. Options a and e are correct.

Explanation:
A.
The transpiration stream that passes through a plant may follow an apoplastic route, with low resistance to flow, or a cell-to-cell route, in which cellular membranes impede water flow. However, passage of water through membranes can be facilitated by aquaporins thereby decreasing resistance. We investigated the relationship between transpiration, which can be down-regulated by abscisic acid (ABA) or by high humidity, and the osmotic water permeability (Pos) of protoplasts. By using leaf protoplasts of wild-type (wt) Arabidopsis thaliana plants and of mutants that are low in ABA (aba1) or insensitive to ABA (abi1 and abi2), we found that protoplasts from aba1 and abi mutants have very low Pos values compared with those from wt plants when the plants are grown at 45% relative humidity. High values of Pos were found 3 h after the addition of ABA to the culture medium of aba1 plants; addition of ABA to abi plants did not restore the Pos to wt levels. There was no such increase in Pos when excised leaves of aba1 plants were treated with ABA. When the transpiration stream was attenuated by growing the plants at 85% relative humidity, the Pos of protoplasts from all plants (wt and mutants) was higher. We suggest that attenuation of the transpiration stream in whole plants is required for the up-regulation of the Pos of the membranes, and that this up-regulation, which does not require ABA, is mediated by the activation of aquaporins in the plasma membrane.
B.
The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from 14CO2 into glycolic acid, glycine, and serine, while 14C incorporation into 3-phosphoglyceric acid and sugarphosphate esters was depressed. Parallel with this effect, treated plants showed a rise in activity of RuBP oxygenase and glycolic acid oxidase. The rate of photorespiration was increased twofold by ABA treatment at molar while the CO2-compensation point increased 46% and stomatal resistance increased more than twofold over control plants.

What is Solar energy?
Solar energy is the radiant heat and light from the Sun that is captured by a variety of technologies, including solar architecture, solar thermal energy (including solar water heating), and solar power to produce electricity.
It is a crucial source of renewable energy, and depending on how solar energy is captured, distributed, or transformed into solar power, its technologies are often classified as passive solar or active solar. Utilizing photovoltaic systems, concentrated solar electricity.
A building's orientation toward the Sun, the use of materials with favorable thermal mass or light-dispersing qualities, and the creation of naturally ventilated rooms are all examples of passive solar approaches.
Therefore, The ice cubes represents the solar energy.

How is the age of the earth used as evidence of evolution?
Answer:
Explanation:
All radiometric evidence points to the age of the Earth as about 4.54 billion years old. The old age of the Earth is evidence for evolution, a change in the genetic makeup of a population over time.
Answer:
The age of the earth can be used as evidence of evolution because it withholds the past that we are capable of uncovering bit by bit. We excavate fossils buried in the ground which we use accordingly. The fossil record reveals that the deeper you go, the farther back in history you unearth. This is known as the Law of Superposition. With these fossils, we can compare and contrast the anatomy of closely related organisms and possibly uncover vestigial structures. All of which is evidence that evolution has taken place.

A farmer grows several crops on a farm that has mostly shallow, sandy soil, meaning they have
a low water storage capacity and a high infiltration rate. Which of the following irrigation
methods would be the best suited for this farm?
Select one:
O a. Drip irrigation
O b. Surface irrigation
O c. Flood irrigation
O d. Furrow irrigation
For a sandy soil farmer should use drip irrigation method over surface irrigation.
Sandy soils have a low water storage capacity and a high infiltration rate. Therefore they need frequent but small irrigation methods, drip irrigation is most suitable method than surface irrigation.
In other irrigation methods such as Surface irrigation, Flood irrigation, Furrow irrigation water is discharged in quite large amounts but the soil lost it due to the high infiltration rate.
Therefore, for a sandy soil farmer should use drip irrigation method over surface irrigation.

Differentiate between the three dose-response curves, and explain why these curves do not apply to individuals.
Answer:
LD-50: lethal dose 50%, dosage that causes death to 50% of the exposed population
ED-50: effective dose 50%, dosage that causes an effect in 50% of the observed subjects
TD-50: toxic dose 50%, dosage that is toxic to 50% of the observed subjects
These curves do not apply to individuals because it is hard to predict the dosage that will cause a response in an individual, and more practical to predict what percentage of a population will be affected by a certain dosage of a chemical.

The correct pairing of DNA bases is C with G, and A with T. Therefore option D is correct.
DNA (deoxyribonucleic acid) is composed of nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
In DNA, the bases always pair up in a specific way known as complementary base pairing. The bases adenine (A) and thymine (T) form a pair, and cytosine (C) and guanine (G) form a pair.
This pairing is based on the specific hydrogen bonding interactions between the bases:
Adenine (A) always pairs with thymine (T) through two hydrogen bonds.
Cytosine (C) always pairs with guanine (G) through three hydrogen bonds.
This specific pairing of bases is crucial for DNA replication and the accurate transmission of genetic information during cell division and protein synthesis.
The pairing of DNA bases: (D) C with G, and A with T. This pairing reflects the complementary base pairing rules observed in DNA.
