Answer: An Rh+ person can receive Rh+ or Rh-. An Rh- person can only receive Rh- blood
Explanation: the Rhesus (Rh) group has three types, CDE. Of these, only the D locus is of general importance, and this is the one involved when we talk about Rh+ or Rh-. The D allele is dominant and DD or Dd are the Rh+ type, while dd is Rh-.
Rh- people have an immune response to the D and produce antibodies which causes blood clots and this can be life-threatening. Some Rh- people have anti-D antibodies in their blood, but the level is too low to affect Rh+ people transfused with Rh- blood. This is also unlikely because Rh+ is by far the more common type.
A particular problem arises when a mother is Rh- and the father Rh+ because the baby may be Rh+. If this happens the mother will produce antibodies to the foetus’s blood which will kill it if they cross the placenta. This is avoided by giving the mother Rh immunoglobulin injections during pregnancy which switch off anti-D antibody production.
It is rare for the C and E loci to cause a significant immune response.
Answer:
Rh+
blood can receive Rh+ or Rh- blood.
Rh-
blood can receive Rh- blood.

Is energy stored when ATP is hydrolyzed?
Answer: ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy.
Explanation: Mark me as (brainlisti) pls
Answer:
ATP is an excellent energy storage molecule to use as "currency" due to the phosphate groups that link through phosphodiester bonds. These bonds are high energy because of the associated electronegative charges exerting a repelling force between the phosphate groups. A significant quantity of energy remains stored within the phosphate-phosphate bonds. Through metabolic processes, ATP becomes hydrolyzed into ADP, or further to AMP, and free inorganic phosphate groups. The process of ATP hydrolysis to ADP is energetically favorable, yielding Gibbs-free energy of -7.3 cal/mol.[1] ATP must continuously undergo replenishment to fuel the ever-working cell. The routine intracellular concentration of ATP is 1 to 10 uM.[2] Many feedback mechanisms are in place to ensure the maintenance of a consistent ATP level in the cell. The enhancement or inhibition of ATP synthase is a common regulatory mechanism. For example, ATP inhibits phosphofructokinase-1 (PFK1) and pyruvate kinase, two key enzymes in glycolysis, effectively acting as a negative feedback loop to inhibit glucose breakdown when there is sufficient cellular ATP.
Conversely, ADP and AMP can activate PFK1 and pyruvate kinase, serving to promote ATP synthesis in times of high-energy demand. Other systems regulate ATP, such as in the regulatory mechanisms involved in regulating ATP synthesis in the heart. Novel experiments have demonstrated that ten-second bursts called mitochondrial flashes can disrupt ATP production in the heart. During these mitochondrial flashes, the mitochondria release reactive oxygen species and effectively pause ATP synthesis. ATP production inhibition occurs during mitochondrial flashes. During low demand for energy, when heart muscle cells received sufficient building blocks needed to produce ATP, mitochondrial flashes were observed more frequently. Alternatively, when energy demand is high during rapid heart contraction, mitochondrial flashes occurred less often. These results suggested that during times when substantial amounts of ATP are needed, mitochondrial flashes occur less frequently to allow for continued ATP production. Conversely, during times of low energy output, mitochondrial flashes occurred more regularly and inhibited ATP production.[3]

What is a Blood group type?A blood group type may be characterized as the classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. In humans, there are four types of blood groups are there.
A blood group: [tex]I^AI^A or I^AI^O[/tex]. B blood group: [tex]I^BI^B or I^BI^O[/tex]. AB blood group: [tex]I^AI^B[/tex]. O blood group. [tex]I^OI^O[/tex].The blood grouping in humans is an example of co-dominance. The blood group of an individual or offspring is determined by the respective blood group of its parents. Parents with type A blood have the probability to produce any offspring with type O blood in the sense that they fuse their both specific gametes of [tex]I^OI^O.[/tex]
Therefore, it is definitely possible that two individuals with type A blood ever produce any offspring with type O blood.

Explanation:
When people think about the first people in America, they might think of Christopher Columbus or the European colonists; when, in fact, the first people were the Indians. The Cherokee Indians had lived in the lands of what is now the United States for thousands of years before any colonists had ventured over. Little did they know that the new nation that was going to be forming around them, would severely affect the lives of their descendents.
Life before the Trail of Tears but after the arrival of the new Americans was more or less simple for the Cherokees. They spend time hunting and fishing. Some of them even worked on plantations and even owned their own slaves, in an effort to accommodate some of the American ways of living.
this is the rough draft but it needs more if you know anyone who can help it's much appreciated :)

which level of tornado tornados causes the greatest damage?
A: EF0
B: EF1
C:EF5
D:EF10
Answer:
The correct answer is C:EF5.
Explanation:
The Tornado is a meteorological phenomenon that consists of a whirlwind of wind produced as a result of an air rotation of great intensity and of little horizontal extension, which extends from the base of a mother cloud. The Fujita-Pearson scale and the so-called Enhanced Fujita Scale classify tornadoes according to the damage caused. The Enhanced Scale (EF) was a refinement of the old Fujita scale, using wind estimates and better damage descriptions; however, it was designed so that a tornado rated on the Fujita scale would receive the same numerical rank, and was implemented beginning in the United States in 2007. An EF0 tornado, the weakest on the scale, possibly damages trees but not structures, as long as that an EF5 tornado, the strongest, it can cause incredible devastation; it can rip buildings off their foundations, exposing them and even deform skyscrapers. The wind speed in a tornado can reach 500 km / h.

QER question so marks for spelling etc too but if anyone has bullet points of things to include that would be great! :)
Answer:
Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.
In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.
In photoperiodism flowering and other developmental processes are regulated in response to the photoperiod, or day length.

How do the geographic barriers affect the relatedness of species?
Answer:
Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations. This may or may not be sufficient to cause speciation.

A DNA sample contains 30% cytosine. What percentage of the sample would be thymine?
Answer:
30% Thymine
Explanation:
If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.
Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.
Therefore:
30% of A + 30% of T + 20% of C + 20% of G = 100% DNA
20% of thymine is present in a DNA sample that contains 30% cytosine.
What is DNA?DNA stands for deoxyribonucleic acid.It is a polynucleotide chain.A nucleotide consists- a nitrogenous base, deoxyribose sugar and phosphate group.Nitrogenous base are of two types- Purines(Adenine and Guanine) and Pyrimidine(Cytosine and Thymine).Adenine pairs with Thymine and Guanine pairs with Cytosine.What is thymine?Thymine is a Pyrimidine nitrogenous base which forms double bond with Adenine.What is cytosine?Cytosine is a Pyrimidine nitrogenous base which forms a triple bond with Guanine.There is 100% nitrogenous base in DNA.
30% of Cytosine means 30% of Guanine=60%(30+30)
So 100-60=40%(Adenine +Thymine)
So, Thymine and Adenine each will have=20%
Hence, the answer is 20% Thymine.

An important difference between sexual and asexual reproduction is____
Answer:
The number of offspring and the time required to generate them.
Explanation:
The number of off springs and time required to generate them is the right answer.
What is sexual and asexual reproduction?In sexual reproduction, the offspring inherit a combination of genes from both parents, which can lead to the expression of new traits and the evolution of new species. In asexual reproduction, the offspring inherit the same genes as the parent, so there is little potential for genetic variation and evolution.
Asexual reproduction is often seen as less efficient than sexual reproduction because it does not allow for the exchange of genetic material that can help organisms adapt to changing environments.
