There are three main types of rocks: sedimentary, igneous, and metamorphic that form the rock cycle. Hope this helps :)
Other than contributing to potential increase in diversity of species in an ecosystem, exotic species have positive benefits like removing toxins from the soil, regulating erosion, and controlling undesirable species.
Answer:
Biology is the study of Living organisms whereby they are clustered into distribution , origin , behavior , anatomy their physiology and morphology.
Biology as a subject has changed my views and conspiracies about the existence of organisms in their ecosystem .Its like from biology you get to know the meaning of life in details right from the origin to death of the organism .
As a human being I have realized much on how biology helps even beyond the class , since I have learnt the reason why each organism belongs to a certain habitat and specific niche of the ecosystem , I have learnt to respect and conserve such organisms as they deserve to exist in that habitat , and their is an interdependency whether direct or indirect .
Also with the knowledge I have acquired on anatomy and the physiology of organisms , I can do a first aid to an individual who has suffered outdoor pass outs or injuries to reduce the impact of the situation before he or she reaches the hospital .
I believe biology has impacted a very important part of my life and I look forward to take further studies in this field to broaden my knowledge even more .
If a moving object loses mass, how can it keep its momentum constant?
A. by speeding up
Answer:
Yellow smooth - 9
Yellow wrinkle - 3
Green smooth- 3
Green Wrinkle - 1
Explanation:
Let the green color of the seed be depicted by "G" and the yellow color of the seed be depicted by "g"
Let the smooth the seed be depicted by "R" and wrinkled seed be depicted by "r"
F1 cross -
true breeding smooth green plant ( RRGG) and true breeding wrinkled yellow (rrgg)
F1 gamete will be RG, RG, rg, rg
F1 offspring will be RrGg , Thus all F1 offspring will be heterozygous smooth and yellow.
Thus, R is dominant over r and g is dominant over G
F2 Generation –
RrGg x RrGg
Gametes will be RG, Rg, rG, rg
RG Rg rG rg
RG RRGG RRGg RrGG RrGg
Rg RRGg RRgg RrGg Rrgg
rG RrGG RrGg rrGG rrGg
rg RrGg Rrgg rrGg rrgg
R is dominant over r and g is dominant over G
Genotypes are –
RRGG - 1 (Smooth Green)
RRGg-2 (Smooth yellow)
RrGG-2 (Smooth Green)
RrGg-4 (Smooth yellow)
RRgg- 1 (smooth yellow)
Rrgg – 2 (Smooth yellow)
rrGG – 1 (wrinkled Green)
rrGg – 2 (Wrinkled yellow)
rrgg – 1 (wrinkled yellow)
Yellow smooth - 9
Yellow wrinkle - 3
Green smooth- 3
Green Wrinkle - 1
