Answer:
is a result of the absence of macrophages or B cells.
Explanation:
Severe combined immunodeficiency (SCID) results due to the absence of macrophages or B cells that is responsible for the immunity of our body. Severe combined immunodeficiency (SCID) is an inherited immunodeficiency disease (PIDD) that presents in infancy results in a weak immune system that is unable to fight against even mild infections so due the absence of macrophages or B cells, the body is vulnerable to diseases.

Why is The sun is the ultimate source of energy
for all living organisms.'
Answer:
"Sun is the ultimate energy source for all living organisms."
✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.
✴Secondly, sunlight is a good source of Vitamin-D.
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.
✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

What is the function of the enzyme RNA polymerase during transcription?
helps slow down the process of transcription
helps speed up the process of transcription
aids in destroying the mRNA sequence that was read
aids in packaging amino acids for use at a later time
Answer:
The correct answer is - helps speed up the process of transcription.
Explanation:
RNA polymerase binds to the DNA sequence and copy a single DNA sequence into RNA and helps a single gene to produce hundreds or even thousands of RNA molecules during transcription.
It helps in the speed up the transcription by copying the sequence and producing mRNA for translation process later.

C. Denitrifying bacteria
D. Nitrifying bacteria
Answer:
lightning because it doesnot support freely stated nitrogen to convert in usable nitrogen
The one that essential part of turning nitrogen into a form usable by animals is lightning. The correct option is A.
What is lightning?Lightning is a spark of electricity that occurs in the atmosphere between air and ground. It occurs when two oppositely electrical charges discharge electrostatic energy.
Lightening is no use to animals, instead, it causes damage to houses, animals, and trees when they fall down.
Thus, the correct option is A. Lightning.

Why is it essential for SARS-CoV2 RNA be translated on ribosomes before it can be replicated?
The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome. The protein inserts its C-terminal domain into the mRNA channel, where it interferes with mRNA binding. We observe translation inhibition in the presence of Nsp1 in an in vitro translation system and in human cells.

Why would AZT be a poor candidate to inhibit SARS-CoV2?
Answer:
Due to its less effectiveness.
Explanation:
Azithromycin would be a poor candidate to inhibit SARS-CoV2 due to its less effectiveness. Azithromycin has no effect on the virus because this antibiotic can only attack on the structure of bacteria. Azithromycin is an antibiotic which is used for the treatment of a number of bacterial infections not viruses. They are not designed to destroy the structure of virus but for the bacteria.

mapa mental sobre El origen de las especies
El origen de las especies, cuya primera edición apareció en 1859, es el libro más conocido de El biólogo británico Charles Darwin. En el libro, Darwin expone su teoría de la evolución:
Afirma que toda la vida en la Tierra tiene un ancestro común. Que la selección natural es el mecanismo principal para la evolución de las especies.El libro está considerado como una de las obras científicas más importantes de la historia. Causó revuelo en el momento de su publicación porque atribuyó la riqueza de la forma de vida en la Tierra a un proceso mecánico más que a una inteligencia sobrenatural. Es cierto que otros habían sugerido previamente que podría haber cosas como la evolución o la selección natural, pero "El origen de las especies" es el primer trabajo que extrae la mayor consecuencia de estos conceptos.

C)how Trichoplax adhaerens moves using its cilia
B)how Trichoplax adhaerens eats by engulfing its food
CAN I GET ANSWERS ASAP PLS
Answer:
D - How trichoplax adhaerens eats by engulfing it's food
Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D. It is a process by which the cells engulf the food that is coming from the outside of the cell.
What is phagocytosis?The cell has many organelles, such as the lysosome, vacuole, cell nucleus, etc., but each organelle has a special function, and one organelle cannot take over the function of another organelle. The lysosomes have a very unique and acidic environment that destroys the organelles, such as old organelles, and kills viruses, etc.
When outside food particles or pathogens enter the cell, they enter as a vacuole, and the cell transports them from the outside to the inside through a variety of processes. The cell then eats them, a process known as phagocytosis, and if it is a virus, the lysosome degrades it.
Hence, Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D.
