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.
There are different kinds of tissues in the body.
Insect flight muscles is found in the Mitochondria.Cells lining the respiratory passages is found in the cilia and flagella .White blood cells that engulf and destroy invading bacteria linked to the Lysosomes.Leaf cells of cacti are linked to the ChloroplastsGoblet cells lining the intestinal tract that secrete mucus linked to Golgi apparatus.Pancreatic cells that are responsible for creating several digestive enzymes linked to proteins and Ribosomes.What are the types of tissues?There are known to be 4 main types of tissue.

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

Which of the following would eat a hamburger with lettuce on it?
A) carnivore
B) detritivore
C) herbivore
D) omnivore
An Omnivore would eat a hamburger (animal) with lettce (plant) on it. Therefore option (D) is correct.
What do you mean by Omnivore ?
An animal classified as an omnivore consumes both vegetation and other animals. Some omnivores, such as carnivores that consume herbivores and other omnivores, will hunt and consume their meal. Some individuals are scavengers and will consume dead things. Many people eat eggs that belong to other species.
Not all types of plants are consumed by omnivores. Omnivores, unlike herbivores, are unable to digest some components of grains or other non-fruit-producing plants. However, they are able to eat fruits and vegetables. In this simulation, some of the insect omnivores are pollinators, which are crucial to the life cycle of several plant species.
Therefore, omnivore is the correct option (D) among other options.

Explanation:
Duckweed is a tiny floating aquatic plant that can reproduce so rapidly that it can completely cover the surface of small fish hatchery ponds. One proposal to limit the growth of this invasive plant is to use colored panels to shield the ponds, inhibit photosynthesis, and kill this pest. What color filters would you order for the panels in this project
Answer:
Green color filter
Explanation:
It is given that Duckweed grown on water and covers all part of the pond very rapidly. In order to limit their growth is proposed to use a color panel so as to shield the ponds and inhibit photosynthesis process and also kill the pests.
So a green colored panels can be used to shield the pond. This is because the photosynthetic pigments such as the chlorophylls absorbs all the green frequencies of the visible light except for the wavelength that corresponds to the green color. Therefore, by using a green filter, the wavelength corresponding to blue, yellow, red and purple colors are absorbed. Thus the plants would not be able to use the green light for the process of photosynthesis. This would help in limiting the growth of the duckweeds.
Individual amoebae of the slime mold Dictyostelium discoideum aggregate to form a spore-producing fruiting body. Cheaters make spores, but do not contribute to the stalk. Since many more spores with cheating genotypes are dispersed, they have higher fitness. Why does directional selection not lead to fixation of the cheater genotype
Answer:
It is an example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness.
Explanation:
Natural selection:
The population contains both superior as well as an inferior organism where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
The given question is the example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness. Directional selection will not lead to fixation of cheater genotype. This is because cheating can be controlled through high relatedness in social groups, resulting from kin discrimination.
It is controlled through positive pleiotropy, where the cooperation gene has an additional vital function. Cheating will be controlled if stalk vs. spore is a result of environmental, not genetic factors. An example, spore fate can be a result of the position in the mitotic cell cycle.

nvision in a family the mother has breast cancer and retinoblastoma (both conferred by recessive alleles on chromosome 17, and the two loci are on the same arm of this chromosome and 3 centimorgans apart), while the father does not carry any of these recessive alleles. What is the probability of their daughter having both cancers
Answer:
0%
Explanation:
Two genes/loci are linked when they are located on the same chromosome. Recombination, also known as crossing over, refers to the exchange of genetic material between non-sister chromatids during meiosis. One centimorgan (1 cM) is a genetic measurement of the distance between two loci on the same chromosome in which 1% crossing over occurs. In this case, the mother is an unaffected carrier who has one copy of both linked mutations (i.e., of both breast cancer and retinoblastoma mutations), thereby the expected frequency of recombination in the female meiosis is 3% (3 cM). Moreover, and since the father is an unaffected individual (who does not carry any of these recessive alleles) and both breast cancer and retinoblastoma conditions are caused by recessive somatic mutations, the probability of their daughter having both cancers is 0%, (offspring always receive one copy of each autosomal/somatic chromosome from the mother and one copy from the father).

what is the relationship between bacteria and the bacteriophage??
Answer:
We have bacteria that live on us, and bacteria have bacterial viruses that live on them. These viruses are called bacteriophages . Viruses differ from bacteria in that they are not made of cells, but instead consist of a piece of DNA (or RNA) packed within a protein coat. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces them cell to produce viral components.

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.

Humans may have Rh blood or Rh- blood. A person who is Rh (R) has a certain type of protein on the red blood cells. A person who is Rh- (r) does not have this particular protein. In humans, Rh dominates Rh-. Normal insulin (I) production dominates abnormal insulin production (i) (diabetes). If both parents are heterozygous for both Rh and normal insulin production, what phenotypes would they produce in their offspring
Answer:
- Rh, normal insulin
- Rh, no insulin
- Rh-, normal insulin
- Rh-, no insulin.
Explanation:
This question involves two genes; one coding for Rhesus factor and insulin product. The allele for Rh blood and normal insulin dominates that of Rh- and no insulin.
According to this question, if both parents are heterozygous for both Rh and normal insulin production and cross, i.e. RrIi × RrIi, the following phenotype of offsprings will be produced (see punnet square):
- Rh, normal insulin (R_I_)
- Rh, no insulin (R_ii)
- Rh-, normal insulin (rrI_)
- Rh-, no insulin (rrii)
