Explanation:
Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

scientist have been measuring increasing levels of greenhouse gases in Earth's atmosphere. How do increasing levels affect the atmosphere?
Well, we have a book to write on this topic but imma explain it briefly plus simply.
Global warming emphasizes the environment with rising temperatures, water shortages, increased fire threats, droughts, weeds and pest attacks, severe storm damage and salt attacks, to name just a few.(In simple words)Now, we'd go briefly and discuss some common affects briefly :
Hotter days - The climate is getting more and more warmer and year 2015 was the hottest year ever record throughout the history. The Earth's temperature had already warmed by 1°C which is really dangerous. Rising sea levels - Rising sea levels due to climate change is the biggest problem causing natural calamities. Increased ocean temperatures are melting glaciers and ice caps all over the world. Melted ice increases the volume of water in our oceans. Warmer temperatures also result in the expansion of the water's mass, which causes sea levels to rise, threatening islands and coastal cities.More frequent and intense extreme weather - Extreme weather events like bushfires, cyclones, droughts and floods are becoming more common and more aggressive as a result of global warming.Hope it helps <3

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

A scientist is studying a radioactive element that has a half-life of 63 years. It will take 63 years, In 189 years, one-eight of the sample will be left.
what is the meaning of half life ?A radioactive element is defined as the material when it changes its atomic number or weight by emitting energy, the energy may be either Alpha, beta, or gamma forms of radiation.
Alpha is a Helium nucleus, a beta particle is an electron and a gamma is high energy electromagnetic radiation. Half-Life can be defined as the time required by which the radioactive substance to split into a different substance.
The half life was first discovered by Ernest Rutherford and represented by the Ug or t1/2, If the radioactive element has one-hour of half-life, it means one half of the element would decay within an hour and the remaining part would decay in another hour.

Mt. Pinatubo, a volcano in the Philippines, erupted in 1991. The eruption resulted in the cooling of Earth's surface
for two years.
What can you deduce from the information given?
O Solar energy seeped through the atmosphere,
O The eruption caused sunspot activity to increase.
O The volcano released a lot of sulfur dioxide and ash,
O Greenhouse gases caused the cooling of Earth's surface.
Answer: this is easy, i think
Explanation:
The volcano released a lot of sulfur dioxide and ash
According to question, "C" which is the volcano released a lot of sulfur dioxide and ash.
What is a volcano and what causes its eruption?When magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge.
Thus, the volcano released a lot of sulfur dioxide and ash is correct.

which of the following is not true about an allele?
A. alleles are found at the same place on a chromosome
B. alleles have a dominant and recessive form
C. an allele is never independently assorted and passed down randomly
D. and allele is one of two or more forms of a gene
Answer:
C
Explanation:
I guess it's C but not conform
C. An allele is never independently assorted and passed down randomly.
What is an allele?Alleles are found at the same place on a chromosome, known as a locus. They can have a dominant and recessive form, meaning that one form of the allele may be expressed over the other in the phenotype of an organism. An allele is one of two or more forms of a gene, which are variations of a particular gene that can produce different traits in an organism.
However, alleles are not always passed down randomly. In meiosis, the process of cell division that produces gametes (sex cells), the alleles of a gene are independently assorted and passed down to the offspring. This means that each gamete receives one copy of each allele at random, which can result in a mix of alleles in the offspring. However, the exact combination of alleles that an offspring receives depends on the combination of alleles that its parents had, which can influence the probability of certain alleles being passed down.

How does soil erosion affect streams and rivers?
Explanation:
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.

Before cells divide, they must replicate their entire genome. Explain why
replication of the genome prior to cell division is important.
Each time a cell divides into two daughter cells, its full genome is duplicated; for humans and other complex organisms, this duplication occurs in the nucleus. This minimizes the incidence of errors (mutations) that may greatly affect the resulting organism or its offspring. ...

Answer:
In order for all of the cells in your body to maintain a full genome, each cell must replicate its DNA before it divides so that a full genome can be allotted to each of its offspring cells. If DNA replication did not take place fully, or at all, the offspring cells would be missing some or all of the genome.
