Describe two ways in which the above law protects citizens against human trafficking
Answer:
The law in question is not included so I will include tow different laws and how they protect people from human trafficking.
1. The Victims of Trafficking and Violence Prevention Act (TVPA).
This Act made human trafficking a Federal crime while also establishing rules on how to prosecute human traffickers and getting the victims of trafficking reintegrated into society and protected. Under this Act therefore, citizens are protected because the law would act as a deterrent to a lot of would-be traffickers.
2. The Mann Act of 1910.
Under this Act, it is a crime to make promises to people such that they cross state lines and are then involved in activities they did not sign up for - this is a definition of human trafficking so this law protects citizens from that.
Which epithelial lining is found in the trachea
which organisms replicate cells by mitosis?
a. animals and bacteria
b. bacteria and plants
c. animal and plants
d. archaea and bacteria
e. archaea and plants
Answer:
d.??????????????????
Answer: C!
Explanation: eukaryotic cells may divide via either mitosis or meiosis. only sexually reproducing eukaryotes can engage in meiosis. all eukaryotes — regardless of size or number of cells — can engage in mitosis.
Having no cell nucleus, archaea do not reproduce via mitosis; rather, they procreate using a process called binary fission. So D AND E are eliminated. And so is B because that has bacteria.
SO FINAL ANSWER; mitosis happens in eukaryotes, plant and animal cells

D.life processes of animals
Helppppp I will make brainliest
The process of photosynthesis adds oxygen to the atmosphere. Option C is correct for the given statement. In the atmosphere, nearly 21% oxygen is present.
What is the gas constituent of the atmosphere?In the atmosphere, different gases such as oxygen, nitrogen, carbon dioxide, and water vapour are present. These differ in composition, with oxygen accounting for 21%, nitrogen accounting for nearly 78%, and carbon dioxide accounting for less than 1%.
The oxygen is produced by the process of photosynthesis that is undertaken by green plants. The phytoplankton, algae in aquatic habitats, and plants of the terrestrial ecosystem do photosynthesis because of the presence of chloroplasts.
This oxygen is used by animals and plants for cellular respiration. Others are incorrect options because forest fires increase carbon dioxide in the atmosphere, animals take oxygen from the atmosphere, and rock weathering does not add oxygen.
As a result, option C is the correct answer because photosynthesis produces oxygen for the atmosphere.

White blood cells that engulf and destroy invading bacteria [Lysosomes]
Leaf cells of cacti [Chloroplasts]
Goblet cells lining the intestinal tract that secrete mucus [Golgi apparatus]
Pancreatic cells that are responsible for creating several digestive enzymes (proteins) [Ribosomes]
Explanation:
Mitochondria are cell organelles whose main function is energy generation during respiration. They generate energy in the form of ATP which is then used by the cells and tissues for various metabolic function. Mitochondria are abundant in cells whose energy requirements are high such as muscle cells. Therefore, insects flight muscles will have an abundance of mitochondria.
Cilia are finger-like projections on respiratory surfaces whose sweep-like movements help to move particles and fluids out of the airways. In the trachea, the cilia trap particles like bacteria and viruses and then move these trapped particles along with mucus up to the pharynx where it is either coughed out or swallowed into gastrointestinal tract. Therefore, respiratory surfaces like the trachea will have an abundance of cilia.
Lysosome are cell organelles which function to destroy and digest foreign and cellular proteins in the cell. They have an abundance of proteolytic enzymes which degrade proteins at acidic pH. Therefore, white blood cells that engulf and destroy invading bacteria will have an abundance of ysosomes.
Chloroplasts are plant cells organelles which are the sites for photosynthesis. It is abundant in the leaves of plants where photosynthesis mainly take place. Therefore, leaf cells of cacti will have an abundance of chloroplasts.
Golgi apparatus is a cell organelle that helps process and package proteins and lipid molecules, especially those that are to be secreted outside the cell, packaging them into vessicles. They also make and secrete mucus. Therefore, goblet cells lining the intestinal tract that secrete mucus will have an abundance of Golgi apparatus.
Ribosomes are cell organelles whose main function is to synthesize proteins, both for intracellular and extracellular purposes. Proteins such as hormones, enzymes etc, are synthesized by the ribosomes. Therefore, pancreatic cells that are responsible for creating several digestive enzymes (proteins) will have an abundance of ribosomes.

Suppose that you compare the amount of food needed by four groups of lizards, each of which has a metabolic rate that is expected for its body size. There are 10 lizards weighing 10 g each, 5 lizards weighing 20 g each, 2 lizards weighing 50 g each, and a single 100-g lizard. Assuming equal digestibility, similar food, and so on, the _______ lizards need the most food.
A. 10-g
B. 20-g
C. 50-g
D. 100-g
E. All of the above need the same amount of food.
Answer:
The _10 gr__ lizards need the most food.
Explanation:
Metabolic rate: Refers to the energy used by the organism during a period of time. Small animals have higher metabolic rates than big animals to maintain energy levels. In general, small animals are more active than big animals. The amount of food needed by the animal to keep energy and body mass depends on the individual´s metabolic rate.
If small animals have a higher metabolic rate than big animals, then they need more food to maintain their energy levels. The relationship size-metabolic rate can be applied to different species -such a mouse and an elephant-or to the same species -like the one of the exposed example-.
So, in comparison, and considering their body sizes, 10 g lizards have the highest metabolic rate, meaning that they need the most food -again, considering their sizes- to keep energy and body mass constant.

6. Discuss how polymorphism in the cnidarians might have influenced adaptive radiation of the group.
Answer:
Explanation:
The class Anthozoa of the phylum Cnidaria includes a wide range of corals and marine animals. Cnidarian polymorphism: Medusa and Polyp are two phases wherein cnidarians vary their morphology for adaption, resulting in them mostly existing as dimorphic zooids. Finally, as the medusa stage develops, these colonial polyps might differentiate into specialized forms.
Medusa forms possess velum, manubrium, defined radial canals, and accompanying ring canal, as well as other components like ocelli and statocysts, demonstrating their adaptability to their survival. Polyp stages have adaptive radiation, including such stolon and structures like hydranth and planula, to help them escape predators. Other structures commonly found include gonangia and gonopore.
Hydra is a kind of freshwater animal belonging to the class Cnidaria. Hydra is diploblastic, which implies it has two tissues: nerve and muscular tissue. Mesoglea is a gel-like material that separates the epidermis and the gastrodermis. Charles Darwin used these finches in his experiments to illustrate how changes in the environment, allelic alterations, and mutation effect affected the species' adaptive radiation.

Answer:
The Orchids is the diversified structures of flowers, in fact, they have unique feature. Even with the pollination, they have several mechanisms of pollination. Few of them include:
1. Few orchids have self-fertilization where the anther converts from solid-state to a liquid state without any aid of an external pollinating agent.
2. In others, self-pollination occurs, when the caudicles dry the pollen fall on the stigma.
3. This happens through an external pollinator resulting in a diversity of species.
4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.
5. These types depend on ants and other insects to get pollinated.
6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.
