The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the immune system, and complementary to the circulatory system. It consists of a large network of lymphatic vessels, lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues. The vessels carry a clear fluid called lymph (the Latin word lympha refers to the deity of fresh water, "Lympha") back towards the heart, for re-circulation.
Unlike the circulatory system that is a closed system, the lymphatic system is open. The human circulatory system processes an average of 20 litres of blood per day through capillary filtration, which removes plasma from the blood. Roughly 17 litres of the filtered blood is reabsorbed directly into the blood vessels, while the remaining three litres are left in the interstitial fluid. One of the main functions of the lymphatic system is to provide an accessory return route to the blood for the surplus three litres.
The other main function is that of immune defense. Lymph is very similar to blood plasma, in that it contains waste products and cellular debris, together with bacteria and proteins. The cells of the lymph are mostly lymphocytes. Associated lymphoid organs are composed of lymphoid tissue, and are the sites either of lymphocyte production or of lymphocyte activation. These include the lymph nodes (where the highest lymphocyte concentration is found), the spleen, the thymus, and the tonsils. Lymphocytes are initially generated in the bone marrow. The lymphoid organs also contain other types of cells such as stromal cells for support. Lymphoid tissue is also associated with mucosas such as mucosa-associated lymphoid tissue (MALT).

A New energy is produced by plants during photosynthesis
B charge amount of energy are we listen to the environment during photosynthesis
C Energy from sunlight is destroyed as its powers photosynthesis
D Energy input from the environment is Stored in food molecules during photosynthesis
The correct option is D : Energy input from the environment is Stored in food molecules during photosynthesis.
What is Energy?
Energy is defined as the ability or capacity to do work.
Energy is measures in a unit called joules.
A change in energy can be explained as "energy input from the environment is Stored in food molecules during photosynthesis".
During the process of photosynthesis, light energy from the Sun is used by the plant to produces food molecules from carbon dioxide and water. Hence, light energy is changed to chemical energy in photosynthesis.
In conclusion, photosynthesis converts energy input from the environment into food molecules.

Which phase of the cell cycle begins after G₁ phase is complete?
A. Cytokinesis
OB. G2 phase
OC. M phase
OD. S phase
The S Phase takes place after when G1 phase is completed.
The cell cycle generally composed of four phase that are G1, S, G2 and M (Mitotic phase) G1, S, G2 phases are the part of interphase.
A cell divides Into two daughter cells as a result of a sequence of events known as the cell cycle, or cell-division cycle. These occurrences include the duplication of its DNA and a few of its organelles, followed by the cell division process, which involves dividing the cytoplasm and other parts of the parent cell into two daughter cells.
DNA synthesis or replication takes place during the S phase of a cell cycle, which happens during interphase and comes before mitosis or meiosis. By doing this, a cell’s genetic material doubles before it begins mitosis or meiosis, providing enough DNA for the cell to divide into daughter cells. Only once the cell has grown sufficiently to contain twice as much DNA and has crossed the G1 checkpoint does the S phase start. Until this occurs, p16, a protein, stops S phase.

The ability to manage emotions and behaviors in response to challenging events is called (c) self-regulation.
Emotions are the state of mental expressions that are influenced by various incidents and experiences. The different emotions can be happiness, sadness, anger, frustration, irritation, surprise, joy, etc. These emotions can be expressed using various responses.
Self-regulation is defined as the psychological phenomenon of controlling one's response to a situation and the emotions generated due to it. The term itself is self-explanatory for the phenomenon it demonstrates. For example, upon feeling angry on any situation if a person choses to stay calm and quiet instead of fighting and yelling, then that is self-regulation.

Gregor Mendel's observation of pea plants that were either round or wrinkled, yellow or green, gave rise to the concept of a dihybrid cross.When two heterozygous people are crossed, the offspring's genotype and phenotypic ratios will be predictable. Crossing heterozygous parents would result in an estimated phenotypic ratio of 9:3:3:1.Deviations from these predicted ratios may point to a relationship between the two features or to a non-Mendelian method of inheritance for one or both of the traits.The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram.16 different genotypes will be formed.

Human transportation enabled a species of beetle to move from Asia to
North America. This beetle feeds on a particular species of flowering
trees. In its native habitat, predators control its population. However, the
beetle has fewer predators in North America.
What kind of organism is this beetle, in the new ecosystem? What would
its effect be on flowering trees?
The first instances of an exotic long-horned beetle destroying ornamental trees were in Chicago and New York City. Since then, beginning in 1996, reports of this pest have been made throughout the majority of the northeastern states as well as in California. Native to Asia, the Asian Long-Horned Beetle (ALB) decimates a wide variety of tree species, including poplars, maples, elms, and mulberries. Large and noticeable, these beetles can be easily identified by their horns or antennae. This insect harms the ecosystem around people by destroying priceless park and shade trees as well as damaging or even destroying forest trees with high economic worth (e.g., sugar maples in the northeast USA). Physical hazard from falling branches or trees during wind and/or ice storms is also posed to people and vehicles by the structural weakness of trees caused by tunneling larvae.

A sledgehammer has a mass of 3.5 kilograms. What net force, to the nearest whole newton, will a person need to apply to accelerate the sledgehammer at a rate of 4.0(m)/(s^(2)) ?
Record your answer in the boxes below. Be sure to use the correct place value.
Force is equal to mass multiplies with the acceleration.
So, the correct answer is 14 N.
What is Force?Force is the push or pull of an object which cause changes in velocity or to accelerate with mass. It is a vector quantity which means it has direction as well as magnitude.
A force is usually denoted by the symbol F. Below equation is derived from the second Law of Newton.
F = m·a
where F = force, m = mass, and a = acceleration.
For above example,
Mass= 3.5 kg
Acceleration (a)= 4[tex]m/s^{2}[/tex]
so, F=3.5*4= 14N
The SI unit of force is the Newton (N). Other units of force include dyne, kilogram-force (kilopond), poundal and pound-force.
Thus, Force is equal to mass multiplies with the acceleration.
So, the correct answer is 14 N.
