Answer:
One branch of biology, called taxonomy, focuses on the classification of living things. Taxonomy is the study of relationships between living things and the formal classification of organisms into groups based upon those hypothesized relationships. Organisms are classified based upon their similarities and differences.

C. A few Hours ago
D. At least 5 hours ago
A dead body that has a temperature of 90°F mist have died almost immediately before it was found
What is temperature?Temperature is the degree of hotness or coldness of a body.
The average temperature of the human body is around 90° F.
At death, the body begins to grow cold as a result of cessation of metabolic activities.
Therefore, a dead body that has a temperature of 90°F mist have died almost immediately before it was found

D)
black
Answer:
Option B) Smooth
Explanation:
sharp image is formed when light reflects from a(n) smooth .
A sharp image is formed when light reflects from a smooth surface.
What is reflection?A reflective image is formed when light bounces off a reflective surface.
Reflective images can be sharp or blurred depending on the surface on which the light rays bounce from.
When the surface is rough, blurred images are formed. On the other hand, sharp images are formed from smooth surfaces. Sharp images are formed by mirrors because they have smooth surfaces.

Which condition can increase a plant's rate of transpiration
Open stomata can increase the plants rate of transpiration.
What is transpiration?Transpiration refer to the process by which water move all through the plant and its evaporated from aerial parts like leaves, stems and flowers. Water is very essential for plants but only a small amount of water taken up by the roots and this is use for plants growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
Open stomata allow the evaporation of water to the atmosphere.
Therefore, Open stomata can increase the plants rate of transpiration.

which codon in the sickle cell DNA is altered: 1st , 2nd or 3rd
Answer:
Mutation in one exon: 1 amino acid will be replaced by another one; variable consequences depending on the amino acid: most of the time a silent mutation; but the Sickle-cell anemia is due to a mutation at the 6th codon of the β gene (Glu->Val).
Explanation:
i googeld it
Codon in the sickle cell DNA is altered by a single nucleotide substitution that is from GAA to GUA that is in option 2, which is a change from the nucleotide adenine (A) to uracil (U) and this takes place in the beta-globin gene. option 2 is correct answer.
What is the significance of sickle cell anemia?The codon for glutamic acid is GAA is present in normal hemoglobin and changes to GUA in the sickle cell variant due to the A to U substitution at the nucleotide of the codon, and this single nucleotide substitution in the beta-globin gene leads to a change in the amino acid sequence of the protein and a change in the cell structure . This can lead to a variety of health problems, such as anemia and pain and other kidney related diseases.
Hence, a codon in the sickle cell DNA is altered by a single nucleotide substitution that is in option 2 , which is a change from the nucleotide adenine (A) to uracil (U) in the beta-globin gene, so here option 2 is correct answer.

Oxygen acts as the thermal electron acceptor by combining with electrons and blank to form blank
Answer:
H+ ions // water
Explanation:
Start with the temperature at 25 ºC and the pH at 7. Do not vary these parameters while testing for substrate (Initial Lactose) concentration, as they are environmental controls. Substrate (Initial Lactose) concentration is in mg/dL.
Vary the substrate (Initial Lactose) concentration by 250 mg/dL, starting with 0 mg/dL.
Click the green ‘Run’ button.
After the experiment runs, click the graph between 2 and 4 minutes and move it until the time underneath the graph shows ‘Minutes: 3’ and hold it there.
Answer:
The results show that the increase in the substrate concentration is increasing the rate of the reaction. We can see that the reaction rate has increased to 2.88mM/min. After this even if we increase the substrate concentration
Which is a reason for antimicrobial resistance being higher in a biofilm than in free-floating bacterial cells
Biofilms are resistant to antimicrobial chemicals due to genetic diversity.
How do biofilms increase antibiotic resistance?Biofilms are considered as a reservoir of genetic diversity. The emergence and spread of antibiotic resistance genes increase in biofilm due to horizontal gene transfer (HGT).
HGT can happen through the transfer of plasmids among microorganism cells in a biofilm through conjugation so that's why the antimicrobial resistance is higher in a biofilm than in free-floating bacterial cells.

Top-level predators help keep the number of many species in balance. These predators would belong to which group? A. invasive species B. keystone species C. dominant species
keystone species which keeps the number of other animal population in
control and low in the entire ecosystem. They play an important role
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
These predators would belong to keystone species. The correct option is B.
Thus, Predators at the highest levels are frequently regarded as keystone species in an ecosystem. Compared to their biomass or abundance, keystone species have a disproportionately strong influence on the composition and operation of their ecosystem.
They are essential in maintaining the ecosystem's balance and preventing the overpopulation of particular species by controlling the populations of other species there.
The dynamics and biodiversity of the ecosystem can be significantly impacted by the removal of a keystone species.
Thus, These predators would belong to keystone species. The correct option is B.

What is a Concussion?A concussion is a traumatic brain injury that affects your brain function which may be as a result of a blow to the head etc.
The brain is regarded as the center of the nervous system and is a very important and delicate organ. During concussions, the brain function gets reduced which should be checked to avoid damage to other cells.
This can be done by medical follow-up to ensure there is no internal bleeding or damage to brain cells and if there is to start immediate treatment for the survival of the patient.

The branching roots of the mangrove trees slow down the flow of water and help in depositing the sediments which prevent coastal erosions.
Mangroves are halophiles and can grow in saline habitats. They grow worldwide and occur in tropical, and subtropical regions, and are also found in some temperate coastal areas. Mangroves have a complex root system and they are adapted to low oxygen conditions.
The mangroves in Sunderbans are the largest ecosystem in the world. It is the habitat of the largest predator in Asia, the tiger. The name Sunderban comes from Sundari, Heritiera fomies, the mangrove trees which are in abundance in that area.
