Answer:

The law of conservation of mass

Explanation:

In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so the quantity can neither be added nor be removed.

how can a person with sickle cell disease be benefited if they were diagnosed with malaria? someone please help ill give brainliest

Answers

infected sickled red blood cells create a hostile environment for the plasmodium parasite in malaria. The sickle cells have membranes, stretched by their unusual shape, that become porous and leak nutrients that the parasites need to survive and the faulty cells eventually get eliminated quite fast by the organisms, destroying the parasite along the way.

What is true about the two daughter cells formed after the binary fission of a bacterium cell?
A) They have the same primary DNA but may have different plasmids.
B) They have variations in the primary DNA but may have a different set of plasmids.
C) They have variations in the primary DNA but have the same set of plasmids.
D) They have the same primary DNA and the same set of plasmids.

Answers

Answer:

Explanation:

They have the same primary DNA but may have different plasmids.

The two daughter cells which are formed after the binary fission of a bacterial cell have the same primary DNA but may have a different set of plasmids. Thus, the correct option is B.

What is Binary fission?

Binary fission is a type of asexual reproduction where a cell body is separated into two different bodies.

During binary fission, the genetic material of an organism is duplicated in the parent cell which enables the two new organisms formed to be able to contain the separate copy of DNA in their nucleus.

In a bacterium cell, when the two daughter cells are formed after the process of binary fission, they contain the same primary DNA but have different plasmids.

Therefore, the correct option is B.

Count the number of new species that form in each group beginning at 60 mya (the first three species in each group were present around 64 mya, the first time period sampled, so we don't know when those species first appear in the fossil record).

Answers

Answer:

hello your question has some missing information attached below is the missing information

answer :

New planktonic larvae species = 10 species

New Non-planktonic larvae species = 26 species

Explanation:

calculate for the number of new species that form in each group

From the question it can seen that 3 species were present before 60 mya in each set

hence to calculate for the number of new species that form in each group

= Total number of species - number of species present at the beginning of 60mya

Group 1 ( New planktonic larvae species )

= 13 -3 = 10 species

Group 2 ( New Non-planktonic larvae species )

= 29 - 3 = 26 species

Land warms up faster than the sea.
A. True

Answer: Solar radiation is absorbed more by land surfaces than by water. Solar radiation from its surface is reflected from water and returned to the environment. Keeping the land surface warm, as well as the vegetation for energy, because land absorbs much more solar radiation. The warmer the surface of land, the quicker it warms.

The antibiotic rifampicin blocks transcription in many bacteria. In the presence of the antibiotic, adding sigma factor has no stimulating effect on RNA synthesis. A footprinting experiment on a rifamycin treated sample shows that the polymerase remains located at the promoter site in the presence of eNTPs and Mg2 ion. What step of transcription is rifamycin likely to block

Answers

Answer:

transcription initiation

Explanation:

Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:

1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.

2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence

3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).

In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.

Which method would be best suited for neutralizing the acidic components of waste?

a. Incineration Incineration
b. Discharge to sewers, streams, and rivers Discharge to sewers, streams, and rivers
c. Chemical treatment Chemical treatment
d. Biological treatment

Answers

Answer: The method best suited for neutralising the acidic components of waste is chemical treatment. Option C.

Explanation:

Chemical wastes are seen during industrial processes. These wastes include: acids, alkalis, organic solvents, detergents, oils, dyes and heavy metals ( example; mercury, copper and lead). Normally, these wastes should be treated and made harmless before they are emptied into the rivers, lakes and seas. If not treated, the effect of these chemicals on the aquatic ecosystems is extremely harmful.

CHEMICAL TREATMENT of waste is a procedure which is carried out on dangerous acidic waste products to change its chemical properties by neutralisation with basic solutions. Neutralisation is a chemical reaction between a base and an acid. The products formed are salt and water which are less harmful to the ecosystem.

The ACIDIC components of the chemical wastes should be neutralised with an appropriate base solution before disposal to avoid it's harmful effects on the aquatic ecosystems. This is because most chemical wastes are non- biodegradable.

(from Crime, its Causes and Remedies by Cesare Lombroso, 1911) The influence which is most apt to produce a disposition toward rebellion and crime is that of a relatively moderate degree of heat. This is confirmed by a study of the psychology of the peoples of southern Europe, which shows us that they tend to be unstable, and to subordinate the interests of the community and state to the individual. This is doubtless because heat excites the nervous centers as alcohol does, without, however, arriving at the point of producing apathy; and further because the climate, without removing human needs entirely, reduces them by increasing the productivity of the soil and at the same time diminishing the necessity for food, clothing, and alcoholic drinks.

After studying children who watched hours of television after school, one researcher found that watching several hours of television every day was often linked to childhood obesity and lack of physical activity. Childhood obesity is a "complicated and sociopolitical issue," and parents, teachers, community leaders, and governmental leaders can work together to encourage youth to make healthier decisions. As childhood obesity rates continue to be rise, scientists believe that one important factor in making a difference will be educating families, especially in poverty-stricken areas (James 5).
