there are several causes of negative effects when there are endangered species but the number one reaseon is if they die it slowly kills the ecosystem one animal at a time if that animal is part of a food system of life chain.
Explanation:
i hope this helps your welcome boos :) <3
When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.
Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage.
The mutation of sickle cell anemia. Red blood cells.

which could describe the properties of sedimentary rock?
Answer:
Sedimentary rocks contain rounded grains in layers. The oldest layers are at the bottom and the youngest layers are at the top. Sedimentary rocks may contain fossils of animals and plants trapped in the sediments as the rock was formed.
Explanation:
Sedimentary rocks are formed by the accumulation and lithification of sediment, which can include sand, mud, and organic matter.

Answer:
The correct answer is - glucose, respiration and oxygen in order.
Explanation:
The food we eat contains various nutrients mainly, carbohydrates, protein, and fat. The carbohydrate that is we eat has glucose as the primary product and also the substrate in the process known as cellular respiration.
Cellular respiration is a process in which glucose molecules are broken down in order to provide energy in the form of ATP with the help of oxygen. It is called aerobic respiration as it required oxygen for the complete oxidation of the substrate.

what is a monera? Give me explanations
Answer/Explanation:
Monera is an outdated/old-fashioned classification that describes a kingdom of prokaryotic organisms. Nowadays, we split prokaryotic organisms into two kingdoms: bacteria and archaea.
Monera describes organisms that do not contain a true nucleus, including all species of bacteria, archaebacteria, and some cyanobacteria. It does not contain eukaryotic single celled organisms like fungi or protists.
Answer:
Monera is a kingdom that contains unicellular organisms with a prokaryotic cell organization, such as bacteria. They are single-celled organisms with no true nuclear membrane. The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866

You run 30 PCR cycles using primers that amplify a tandem repeat (let's call it D3T40) on Chromosome 3. Choose all of the statements below that are correct. A. The number of repeats at the D3T40 locus will vary among individuals.B. The size of an individual's amplicons is determined by the number of repeats at the D3T40 locus.C. The primers will anneal to the sequences that flank the D3T40 locus.D. Taq polymerase will amplify the entire length of Chromosome 3.E. About 30 amplicons will be produced at the end of 30 cycles of PCR.F. You can determine the size of an individuals D3T40 amplicons using gel electrophoresis.G. The size of the amplicons produced will vary among individuals.H. The primers used to amplify D3T40 could be used to amplify another locus like the D1S80 locus on Chromosome 1.
Answer:
A b c f and g are true
Explanation:
A is true because when we have different individuals we can observe dna polymorphism.
B is true because the size of the amplicon is determined by the treat count of D3T40 locus
C. Is true because polymorphic sequence are actually flanked by primers
D is false
E is false
G is true
F is false
The statements below that are correct include:
A. The number of repeats at the D3T40 locus will vary among individuals.
B. The size of an individual's amplicons is determined by the number of repeats at the D3T40 locus.
C. The primers will anneal to the sequences that flank the D3T40 locus.
PCR.
F. You can determine the size of an individuals D3T40 amplicons using gel electrophoresis.
G. The size of the amplicons produced will vary among individuals.
It should be noted that DNA polymorphism can be observed among different individuals. Therefore, the number of repeats at the D3T40 locus will vary among individuals.
Also, the amplicon size depends on the number of repeats. Hence, the size of an individual's amplicons is determined by the number of repeats at the D3T40 locus.

The feature may interrupt the sides of a composite-cone volcano is fumaroles. Thus, option B is correct.
What is fumaroles?They are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction.
Fumaroles are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction. Water flows in the form of steam continuously through the cracks of a volcano or volcanic surface because its temperature exceeds 100 °C.
