Answer:
Since a sample of air at 35 ° C and 60% relative humidity holds 26.25 grams / cubic meter of water vapor. The same sample of air at 40 ° C can hold a maximum of 50 grams / cubic meter of water vapor. If the air currently holds 30 grams / cubic meter, then its relative humidity is 60%.
Explanation:
To solve the following question, the following calculations must be performed:
If 40ºC can have a maximum of 50 grams per cubic meter of water vapor, this would imply a total of 100% humidity. Thus, if 35º had 100% humidity, the amount of grams per cubic meter of water vapor would arise from the following calculation:
40 = 50
35 = X
35 x 50/40 = X
1750/40 = X
43.75 = X
Now, if this implies 100% humidity, to determine 60% humidity the following calculation must be carried out:
100 = 43.75
60 = X
60 x 43.75 / 100 = X
2625/100 = X
26.25 = X
Therefore, if with 100% humidity you have 50 grams per cubic meter of water vapor, with 60% humidity you would have 30 grams of water vapor per cubic meter.

Many plants have modified stems that serve various purposes, including storage, protection, photosynthesis, support, propagation, and perennial growth.
What are the functions of modified stems, and explain them with examples?Underground Stem Modifications:
These can be found underground, as their name suggests. They have a variety of uses, including food storage, reproduction, and perpetuation. By having nodes and internodes, they may be distinguished from roots. They support asexual reproduction and the plant's ability to endure a period of hibernation. They offer a defense against animal grazing and environmental stress.Rhizome: It runs parallel to the ground, and its lower portion, capable of producing adventitious roots, can also generate scaly leaves. They have internodes, buds, and nodes. Examples: Turmeric and ginger. The rootstock in bananas is a rhizome that develops vertically.Bulb: Modified bulbs are visible, and the stem is shortened and ringed with scale leaves. Examples: Tulips, Lilies, Daffodils, Onion, GarlicCorm: A short erect stalk with scaly leaves covers it. When compared to bulbs, it is tough. Examples: Colocasia, Yam, SaffronTuber: The fleshy, food-storing stem terminal is present in this instance. Nodes and internodes are present in the stem; however, they are not identifiable because of swelling. Scaly leaves present at nodes can be interpreted as eyes or scars. Examples: Potato, Artichokes.Many plants have modified stems that serve various purposes, including storage, protection, photosynthesis, support, propagation, and perennial growth.

In a case whereby Emmings are small mammals that reproduce quickly. A lemming population often grows so quickly .This example best supports the ideas of option A Malthus Principle of Population.
What is Malthus Principle of Population?The Malthusian principle of population, also known as the Malthusian theory of population, was proposed by Thomas Malthus in his 1798 book "An Essay on the Principle of Population."
According to Malthus, population growth is exponential, while the growth of resources is linear. Therefore, if left unchecked, the population will eventually outgrow the available resources, leading to widespread poverty, famine, disease, and ultimately, population decline.
Malthus argued that there are two types of checks that prevent population growth from exceeding available resources: preventive checks, which are actions that people can take to limit population growth, such as postponing marriage or practicing contraception, and positive checks, which are events that limit population growth, such as famine, disease, and war.

Write a list of the words that directly intervene in the water cycle, that is, that are part of the different states that present the water cycle.
Answer:
Evaporation, transpiration, condensation, precipitation, and runoff.
Explanation:
Evaporation, transpiration, condensation, precipitation, and runoff are the words that directly intervene in the water cycle. The evaporation occurs in the water bodies when the water is heated with the help of solar radiation whereas transpiration occurs from the plant body. When this water vapors goes in the atmosphere, they form clouds by condensation of water molecules and as a result precipitation occurs. Some rain water is absorbed by the soil while the remaining run-off on the surface in the form of streams, lakes and rivers etc.

mention four method of vegetative propagation
Methods of vegetative propagation include cutting, grafting, layering, division, sprouting, etc.
Vegetative propagation is a method of plant propagation that uses vegetative structures such as stems, roots and leaves to create new plants without the need for seeds. There are several methods of vegetative propagation, each suitable for different plant species and desired results. Here are some commonly used methods:
1. Cutting: This involves taking part of the stem or root of the mother plant and placing it in a suitable growing medium. Cuttings develop roots that eventually grow into new plants.
2. Layering: In this method, the plant's branches and stems are bent and partially buried in the ground. Roots develop from the buried part, and when they take root, they are separated from the mother plant and a new individual is formed.
3. Grafting: This technique involves joining the tissues of two different plants, the shoot (the plant of interest) and the rootstock (which provides the root system and support). Two plant tissues fuse and the shoot grows into a new plant with the desired plant characteristics.
4. Sprouting: Similar to grafting, sprouting involves attaching the shoots of the desired plant to a rootstock. New shoots develop from the shoots with the desired plant characteristics.
5. Tissue culture: This is a laboratory-based method of culturing plant cells or tissues in a nutrient-rich medium under controlled conditions. Cells divide and differentiate into whole plants and can be transferred to soil.
These vegetative propagation methods are widely used in horticulture and agriculture to propagate plants with desirable traits or to propagate plants that do not produce viable seeds.

Answer:
That is the greenhouse effect.
The trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
One example of the greenhouse effect that most of us experience in everyday life are the warming of a car's interior when the vehicle is left out in the sun. You've probably noticed that your car is always much hotter inside than the outside temperature if it's been sitting there for a while. This is the same how Earth retains some heat.
The greenhouse effect attributes to global warming, and the Coriolis effect deals with the mass of Earth and its axis of rotation. These answers are already eliminated from the beginning.

When plants release water into the atmosphere it is called transpiration.
TRUE OR FALSE?
Answer:
True
Explanation:
The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.
A single gene with two alleles control variation in haemoglobin type in sheep. There are three different phenotypes corresponding to genotypes S^AS^A S^AS^B and S^BS^B respectively in a flock of 175 sheep the frequency of allele S^A was found to be 0.6 and frequency of allele S^B WAS found to be 0.4
Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.
Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Alleles Frequencies
S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4Genotypes
S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygousWe need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).
Genotypic and Phenotypic frequencies
F(S^AS^A) = p² = 0.6² = 0.36
F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48
F(S^BS^B) = q² = 0.4² = 0.16
Number of individuals expressing each phenotype
S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individualsYou can learn more about the Hardy-Weinberg equilibrium at

Which organisms can reproduce using the process of fragmentation
Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.
In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.
Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.
Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms, annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.
Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.
Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.
Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.
Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D
