Lymph is collected from the body’s organs.
Lymph is a fluid similar in composition to blood plasma. It is derived from blood plasma as fluids pass through capillary walls at the arterial end.
The lymphatic system collects excess fluid that drains from cells and tissue throughout the body and returns it to the bloodstream, which is then recirculated through the body.
Spleen: This largest lymphatic organ is located on your left side under your ribs and above your stomach.

Provide a definition for the process of Crossing Over in Meiosis. Why is crossing
over so important?
Answer: Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched. The two chromosomes contain the same genes but may have different forms of the genes.
Explanation: YES AND B/C Crossing over helps to bring about the random shuffling of genetic material during the process of gamete formation. This results in the formation of gametes that will give rise to individuals that are genetically distinct from their parents and siblings.
All living things on Earth are alike because they:OA. use energy from the Sun to make food.B. breathe air in order to obtain oxygen.C. contain the same five kinds of nucleotides.D. have the same sequence of nucleotide bases.
All living things on Earth are alike because, even though there are a lot of different adaptations which have result in different morphologies, structures and physiological mechanisms, they all contain the same five kinds of nucleotides, but the sequence of nucleotide bases that conform the genes is different.
Only photosynthetic organisms use energy from the sun to make food, and although most of the organisms are aerobic, there are also some anaerobic.
So the correct answer is option C: contain the same five kinds of nucleotides.

Why do light-fur mice survive LESS often on dark rocks, compared to dark-fur mice?
Answer:
for a creature with a lighter fur color it is next to impossible to blend into darker colored environments compared to darker fur colored creatures
The light fur mice survive less on the dark rocks compared to the dark fur mice. The reason is the light fur mice can be easily visible by the Predator and eaten by them.
What is adaptation?An adaptation is a process in which an organism tries to adapt with the environment in order to protect itself from the predator. There are different types of adaptation seen in the animal kingdom, such as mimicry.
An example is mice fur coloration on the dark rocks. Dark rocks have dark coloration. When dark-furred mice live on this type of rock, their colour will mix with the dark colour of the rock. As a result, they can't be clearly visible to the predator's eye. Predators that are present at a distance, such as birds can't distinguish between the rock and the dark mouse's fur. This increases their chance of survival. When a light fur-colored mouse lives on the dark Rock, it can easily be differentiated by the Predator and eaten by them.
Hence, light colour fur mice survives less than the dark fur mice on the dark Rock as they can easily be seen by predators.

THINK IT THROUGH You may recall that soil is classified by several properties such as color, texture, structure, and pH. Many of the processes that produce soil are related to the activities of living things. Do you think that the types of rocks and minerals found in a particular area could also influence the characteristics of the soil? Explain.
Answer:
Yes, the types of rocks and minerals found in a particular area can influence the characteristics of the soil. This is because soil formation is a complex process that involves the weathering and breakdown of rocks and minerals over time.
For example, if an area has a high concentration of granite rocks, which are composed of minerals such as quartz, feldspar, and mica, the resulting soil may be sandy or gritty in texture and have a higher pH due to the presence of minerals that do not easily break down. On the other hand, if an area has a high concentration of limestone rocks, which are composed of calcium carbonate, the resulting soil may be alkaline and have a higher fertility due to the presence of easily broken down minerals.
In addition, the type of rocks and minerals in an area can also influence the structure of the soil. For instance, if an area has a high concentration of clay minerals, which are formed from the weathering of silicate rocks such as feldspar and mica, the resulting soil may have a higher water-holding capacity and be more susceptible to compaction.
Therefore, the type of rocks and minerals in an area can have a significant impact on the characteristics of the soil, including its texture, structure, and pH, as well as its fertility and water-holding capacity.

Which scientific discipline is correctly matched to a contribution to society?
The options are;
A) biology; theory of relativity
B) geology; theory of continental drift
C) ecology; discovering new elements
D) astronomy; developing quantum mechanics
Answer:
B) geology; theory of continental drift
Explanation:
Looking at the options;
-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.
- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.
- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.
-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.
Therefore correct answer is option B

Those with one copy of the dominant allele, which might come from only one parent, will have a dominant phenotype.
What is the difference between a dominant and recessive phenotype?In people who only have one copy of allele, which could also come from one parent, a dominant allele results in a dominant phenotype. A recessive allele requires two copies—one from each parent—in order to result in a recessive phenotype in the individual.
Is the phenotype of AA dominant?A capital letter is used to identify a dominant allele (A versus a). The combinations are AA, Aa, and aa because each parent contributes one allele. The dominant trait will be phenotypically displayed in offspring with either an AA or an Aa genotype, while the recessive trait will be expressed in aa individuals.

1. In this communications setting, the "S" in the S-M-C-R communications model is: B. the theater owner.
2. Digital technologies process information in terms of: zeroes (0s) and ones (1s).
The Sender Message Channel Receiver (SMCR) model of communication was developed and created in 1960 by David Berlo.
Basically, the SCMR was developed from the Shannon-Weaver model of communication of 1949.
The SCMR model of communication comprises four (4) main components and these include;
Sender (S).Channel (C).Message (M).Receiver (R).Sender (S) is the primary source of information (message) or the originator of a message that is being sent to a receiver.
Hence, a sender is simply the producer of a message.
In this scenario, the theater owner is the "S" in the S-M-C-R communications model because he or she serves as the primary source and originator of the the film "TOP GUN 2" to the movie-goer, who is a receiver viewing a trailer.
Digital technologies process information in terms of zeroes (0s) and ones (1s) because raw data usually in text formats are not understood by a computer or digital device.
Simply stated, a computer or digital device process information in terms of binary digits i.e zeroes (0s) and ones (1s) only.

Individuals or population have specific interaction in between them that may affect the species distribution and abundance. Species lives and survive together in a so called inter-specific competition. If the intraspecific competition is stronger between individuals from the same species, species can survive the interspecific competition in between species. Competition from the same species can be active or passive.
Interspecific competition is the survival of different species in a certain habitat. While sharing the same habitat, these different species undergo interaction with each other that affect their population growth and abundance. This is called as ecological community. Specific interaction in between species are competition, predation, herbivory, symbiosis, mutualism, and commensalism. These type of interspecific interactions can be affected by different factors such as reproduction, natural resources, space and nesting sites, competition, and waste and diseases. While competing for survival, these species will have access to common resource that is limited in supply. The outcome of such competition is usually negative. It is always affecting the weaker competitors.

Free lime and natural gypsum, in addition to soluble salts, are frequently found in the C horizon. Therefore, option (C) is correct.
What is C Horizon?Free lime and natural gypsum, in addition to soluble salts, are frequently found in the C horizon. Unconsolidated material can be found above bedrock at the C Horizon, which is also referred to as the substratum. It has not undergone enough deterioration to be classified as soil, but it is nevertheless considered to be a layer of a soil profile.
The C horizon is often composed of boulders, cobbles, pebbles, and other types of rocks that have not been worn or have only been lightly weathered. Due to the fact that the layers of soil that are found above the C horizon are typically generated from this material, these rocks are referred to as parent rocks.
