QUESTION:

What happens to a cell when It receives the signal to begin apoptosis?​

ANSWER:

Apoptosis begins when the nucleus of the cell begins to shrink. After the shrinking, the plasma membrane blebs and folds around different organelles. The blebs continue to form and the organelles fragment and move away from one another.

Answer:

Lupus refers to autoimmune disease in which the immune system of the body  attacks its normal and healthy tissue instead of virus and bacteria. Symptoms of this disease include inflammation, swelling, and damage to the joints, skin, kidneys, heart, and lungs etc. The main cause of this disease is the environment that triggers Lupus. Chemotherapy and medications such as Nonsteroidal anti-inflammatory drugs and Antimalarial drugs etc are used for its treatment. Due to the disease's complex nature, it is often called "the of 1000 faces". In the united states there are about 16000 new cases of lupus every year. There are different kinds of lupus. This article will focus mainly on systemic lupus erythematosus (SLE), but other types include discoid, drug-induced, and neonatal lupus. Currently there is no cure for lupus, but the symptoms can be managed with care. The treatment aims to manage and prevent flare ups. The exact treatment will depend on how lupus affects the individual. Without treatment, flares can occur that may have life-threatening consequences.

"According to folklore, birds will reject their eggs and young if humans have so much as laid a finger on them. ... No matter how flighty birds appear, they do not readily abandon their young, especially not in response to human touch, says Frank B. Gill, former president of the American Ornithologists' Union."

Answer:

The correct order of size - base pair < gene < chromosome.

Explanation:

Nitrogen base-pair attaches with the phosphate group and a sugar molecule to form a building block of DNA or nucleic acids. Nucleic acids make the gene is the physical and functional unit of hereditary that takes the information from parent cells to daughter cells.

Chromosomes are a structure that appears thread-like and makes the genome with different chromosomes. These structures are made up of wrapped DNA or genes around histone proteins.

Answer:

hello some vital information is missing attached below is the information

answer :

a) nucleophile and alquene carbon.

b) F^- and PO[tex]_{3}[/tex]^-  , Nu  and  C=O

c) fluorescence

Explanation:

The key structural components that are responsible for the following are

a)For  Binding : the key components responsible for binding are nucleophile and alquene carbon.

b) For Covalently modifying : The key components responsible for covalently Modifying are F^- and PO[tex]_{3}[/tex]^-  , Nu  and  C=O

c) For reporting : The key components responsible for reporting is fluorescence and this is because the as seen in the second structure  tyrosine fluorescence is lost

Answer:

what do they mean when they say "spheres" ???

It could be the lithosphere (land) hydrosphere (water) and the atmosphere (air)

Explanation:

if the water molecules are evaporating then there's obviously water involved (hydrosphere)if the water started to evaporate from the ground then lithosphere is involved, too. and the water is rising into the atmosphere, also.

Answer:

An internal disk is located between each vertebra. A gelatinous substance called nucleus pulposus can be found in each disk, which provides cushioning to the spinal column.

Answer:

D. is not very significant because it gives us little insight into human behavior.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

As a scientific concept, race is not very significant because it gives us little insight into human behavior.

This ultimately implies that, race is a scientific concept that holds no significant or absolute value since the nineteenth century.

Hence, the difference between humans shouldn't be described based on race according to the United Nations Educational, Scientific and Cultural Organization (UNESCO).

Answer:

B. an r-strategist

Explanation:

R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size,  5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.

Answer:

Thanks so much for giving the answer!

It is r-stragery though.

k-stratergy produce fewer offspring slowly- such as an elephant.

r-strategey produce offsping rapidly- such as a (nasty) fly.

Answer:

they all come from the same ancestor, and all organisms have DNA made of the same molecules that form our genetic code. DNA in every organism has the bases: A,T,C,G.

Also, don't use this if it's still June 2021 and you're doing ap ex, we might have the same teacher.

All living organisms use the same genetic code. This shows that all organisms share a common evolutionary history.

The genetic code is the set of rules used by living cells to translate information encoded within genetic material into proteins. It is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.

Explanation:

Drilling, extraction and burning of fossil fuels, endangers many desert biomes.  Some deserts are used as dumping grounds for radioactive and chemical waste. Increasing dry periods and lack of vegetation from climate change can lead to more dust storms which further affect plant and animal species.

Answer:

A particular genotype does not necessarily guarantee a particular phenotype. Understanding what factors can change this expression is quite complex.. What is what i believe that above statement meant.

Explanation:

Error is the stochastic variation associated with a particular observation of the phenotype (and is managed by use of replication and and appropriate experimental design). The phenotype is the result not only of the average effect of the different alleles at a given locus across test units and across environments, but is impacted by the interaction between the different alleles and the environments (including genetic backgrounds) in which they are evaluated. Phenotype is not simply the sum of the genotype effect and the environment effect, as indicated in the mathematical formula that you provide.
