Answer:
No
Explanation:
A period is when your body produces a layer of tissue and blood to protect the baby. But the period is when your body is like "oops, false alarm" and disposes of the tissue and blood. During pregnancy, the baby is kept safe by the tissue and blood, that is why women don't have periods during pregnancy.
Answer:
Option (A).
Explanation:
Photosynthesis may be defined as the process in which the light energy has been converted to the chemical energy so that plants can obtain their food with the help of sunlight, carbon dioxide and water.
Photosynthesis is divided into light reaction and dark reaction. The light reaction of photosynthesis is linked together by the mechanism which is similar to the electron transport chain of mitochondria.
Thus, the correct answer is option (A).
Answer:
Explanation:
Lets Tan seed be TT
Red seed be tt
A cross between TT ×tt will produce 4 Tt
TT× tt
!
F1 Tt Tt Tt Tt
a. Tan seed is dominant with an allele TT. It effect dominate that of red seed indicating it is a dominant traits while red seed is a recessive traits.
A dominant trait is a traits that is expressed in the phenotype of an organism the F1 generation are all Tan seeds this shows that the trait is dominant.
The genotype of the F1 melon is Tt in a dominant form
The F2 result follows the mendelian principle where segregation occur leading to a phenotypic ratio of 3:1
72Tan seeds:24red seeds
Where the 72 tan seed has the highest ratio and 24 red seeds has the smaller ratio.
Tt ×Tt
!
F2 TT Tt Tt tt
Phenotypic ratio 3:1
<span>Biotic factors can affect individuals by many factors in a population due to the common places that they might be accustomed to gathering, maybe a cathedral or restaurant or even the electoral voting booth. A choices that a population makes as a group affect more than the majority inhibiting those who oppose until that choice is represented again and the population can change their vote, the ways of natural catastrophe can only be changed by changing what can be seen: putting a plant in a window, rerouting a maple tree, medicating an entire population, and making the most out of living in a homeless shelter.</span>
Answer: Ecosystem Services
Explanation: Simply put,Ecosystem services refer to all the benefits that man enjoys from his relationship with the ecosystem.Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provision,regulation and cultural services that directly affect people, and supporting services needed to maintain the other services. From the availability of adequate food and water, to disease regulation of vectors, pests, and pathogens, human health and well-being depends on these services and conditions from the natural environment.
We depend on nature for our survival – without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. Studies also show that people who spend time in nature tend to be happier than those that don’t. Being outdoor can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the compromise we are making between nature and industrial development.
