Explanation: Just a guess :)
Answer:
a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.
Explanation:
Tay-Sachs, which is a recessive lethal disease ---- Let say the recessive lethal diseases is s
∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.
Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.
Let show an illustration for the above statement.
Let the heterozygous individual be Ts, if Ts cross with another Ts;
we will have:
Ts × Ts
T s
T TT Ts
s Ts ss
the offspring are TT,Ts,Ts,ss
We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).
The green house effect refers to gases trapping the heat energy reflected from earth’s surface.
gases trapping heat energy reflected from the earth's surface.
<u>Explanation:</u>
It is the greenhouse effect that made earth a planet that supports life. if there was no green house effect the earth would have been too cold to live on. Sunlight contains rays like UV and infrared.
UV rays being harmful are blocked by the ozone layer in the stratosphere. Infrared rays that enter the earth’s atmosphere are trapped by the greenhouse gases like carbon dioxide, water vapour, methane etc. the trapped infrared rays help in providing warmth.
Answer:
A flat sheet of connective tissue that extends beyond the muscle fibers to attach the muscle to bone is a TENDON.
Explanation:
Tendon can be described as a fibrous connective tissue which functions mainly to attach muscles to bones hence, playing a major role in the movement of the bone or structure. Tendons also function to connect muscles to other structures like the eye ball.
Contrary to the tendons, ligaments are also fibrous connective tissues which are involved in the attachment of bone to bone. Hence, ligaments play major role in holding the structures and keeping them stable.
