What is phagocytosis in regard to the immune system of humans?

Answers

Answer 1

Answer:

Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.

Answer 2

Answer:

the process by which neutrophils ingest a bacterium

Explanation:

Neutrophils ingest bacteria via a process known as phagocytosis, or "cell eating." (also, I took the quiz)

Why is it possible to do the following party tricks without cheating?
A. Stand with back and heels touching a wall and bend forward from the hips to touch the floor. Return to the upright position without flling or moving the root.
B. Stand facing the edge of an open door with nose and abdomen touching the edge, the feetstraddling the door, and the hands to the sides. Attempt to rise up on the toes.Observe what body motions occur to keep the center of gravity within the base of support whenthese activities are performed without the impediments.

Answers

Answer:

When the body is supported by a wall then it can move in a position counter gravity. The gravity tries to pull the body down and the body responds to it with a slight delay because of wall support.

Explanation:

The body is lifted in upright position with the help of feet. The body rises but after few minutes the gravitational force creates pressure on the body and the body comes down to a natural state. Similarly if the open door is used to perform counter gravity activities then the body will stay for a lesser period in a state because of opened door instead of firm wall support.

what advantage do multicellular organisms have over unicellular organisms?

Answers

Answer:

Explanation:

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism and it has a large surface area to volume ratio while multicellular organisms use many different cells to function to help it transport enough molecules across it membrane.It has a small surface area to volume ratio!

Here’s your answer

The advantage of a multicellular organism over a unicellular organism is that multicellular organisms can grow to virtually any size because the cells integrate their activities and are permanently associated with one another.

Answer:

1. It serves as the functional unit of the nervous system. b. neurons

2. It collects information from the sense organ such as the eyes and the nose. c. peripheral nervous  system

3. It serves as the primary organ of the  central nervous system. f. spinal cord​  

4. It controls or regulates the body's internal brain environment, including the body temperature,  pulse and respiration rate, and bood pressure. e. autonomic nervous  system

5. It is one of the systems that is directly involved in maintaining the normal functions of cells. d. nervous system  

Explanation:

Neuron: Neurons are the structural and functional units in the nervous system.  Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.

Peripheral nervous  system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.

Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.  

Autonomic nervous  system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.  

The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.

What would you look for under a microscope on a slide with meiotic cells if you wanted to identify metaphase I

Answers

Answer:

This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.

Explanation:

During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

Explanation:

Reconstruct the phylogeny that most simply and accurately accounts for the distribution of synapomorphies among ingroup species. Given matrices as small and simple as the above example, one can "build" the tree from the bottom up in a series of sketches, adding clades or branches representing groups with the fewest synapomorphies near the base of the tree and those with the most at the tips. Using the unlabeled phylogeny as a starting point, draw the stepwise construction of a fully resolved phylogeny to account for all of the synapomorphies, and include the synapomorphies that identify each clade (the first one, character 2, is included to get you started; this is shared by all members of the ingroup).

Answers

Complete question:

1). Determine the character states for the following six characters that are present in species OG, 5, 7, 15, 17, 18. Assign the character state found in the outgroup (OG) as a 0 and the alternative derived state a 1; use only two states per character. Example, stem width: 0 = thin, / = thick 1 (Characters and plant species image in the attached files)

2). Score each taxon using the 0 and 1 notation about and add to this matrix (Matrix in the attached files)

4). Reconstruct the phylogeny that most simply and accurately accounts for the distribution of synapomorphies among ingroup species. Given matrices as small and simple as the above example, one can build the tree from the bottom up in a series of sketches, adding clades or branches representing groups with the fewest synapomorphies near the base of the tree and those with the most at the tips.

Answer:

Characters: Stem width: Thick-1 // Thin-0 Leaf edge (shape): Pointed-1 // Blunt-0  Flower base (shape): Narrow-0 // Wide-1 Flower orientation: Downward (Pendant)-1 // Upward (Vertical)-0 Petal color: Purple-1 // Yellow-0 Fruit shape (inset on card, on left): Round-0 // Elongated-1Complete Matrix in the attached filesOrder in the phylogeny reconstruction: OG --> 7 --> 5 --> 15 --> 17 and 18 (tree + evolutive changes in the attached files)

Explanation:

NOTE: You will find the complete activity in the attached files.

The principle of maximum parsimony or maximum simplicity states that among all possible trees within a group of species, the most probable  is the one that requires us to postulate the least number of evolutionary changes. So, to reconstruct a phylogeny we need to choose the tree that requires the less number of changes. To determine the character states for all the six characters, we assigned the number cero to all the characters expressed in the out-group. Thin steam, blunt leaf, narrow flower base, upward flower orientation, yellow petals, and rounded-seeds are all cero states. The other characters are 1.The above information of character state was used to fill in the matrix, specifying which character state belongs to each species according to their traits. The matrix was useful to reconstruct the phylogeny, to identify the autapomorphic trait, and to visualize all the clades.

The diploid number of chromosomes in the mustard plant, Arabidopsis thaliana, is 10. Knowing this, answer the following questions about the stages of mitosis. Part APart complete How many chromosomes will be found in each cell during prophase

Answers

Answer:

10 chromosomes

Explanation:

Ten (10) chromosomes would be found in each cell of Arabidopsis thaliana during prophase.

The prophase stage represents the first stage of the mitotic division immediately after the interphase. A diploid cell has 2n number of chromosomes and the ploidy level of a cell remains intact throughout the interphase to the prophase stage of mitosis.

At the prophase, the chromosomes of a cell only condense and become visible under the microscope. Each chromosome is seen as being consisting of two sister chromatids joined together by a structure known as the centromere.

Hence, the number of chromosomes in the cells of Arabidopsis thaliana would remain the same even at the prophase stage of mitosis.

In sweet pea plants, purple flower color is dominant over red flower color and long pollen grain shape is dominant over round pollen grain shape. Two sweet pea plants that we heterozygous for both flower color and pollen grain shape are crossed with one another. A geneticistis surprised to observe that there are fewer round purple offspring and long red offspring than were predicted by the 9:3:3:1 expected phenotypie ratio Which of the following statements provides the most reasonable prediction to account for the deviation from the expected results?
A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked
B) In sweet pea plants the genes for flower color and for pollen grain shape both exhibit codominance
C) Several mutations occurred spontaneously producing a deviation from the expected phenotypic ratio of the offspring
D) The genes for flower color and pollen grain shape are inherited independently because of the law of independent assortment

Answers

Answer:

The correct answer is - option A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked.

Explanation:

In this given case the result of phenotypes are not as expected and does not follow the law of independent assortment presented by Mendel. It appears to be the case of genetic linkage as it is not following the mendelian law by producing fewer round purple offspring and long red offspring which do not satisfy the expected mendelian ratio of 9:3:3:1. Mutation can lead to failure in producing proteins but could not affect the phenotypic ratio of the plant.

Thus, the correct answer is - option A.

Medel was the Father of Genetics, who gave the laws on independent assortment, dominance, and segregation of the genes.

However, there are some exception that violates these laws, such as genetic linkage is one of the exceptions that violates the law of independent assortment.

The correct answer is:

Option A. in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked

In the given data, the results can be interpreted as:

The Law of independent assortment states that the two or more alleles of different genes are assorted independently.

In the given example, the genetic linkage occurs, which does not follow the ratio of 9:3:3:1. The genetic linkage does not follow the law of independent assortment, which results in fewer purple offspring.

Thus, mutation can cause the failure of Mendel laws and can affect the phenotypic traits of an organism.

Therefore, Option A is correct.
