If you have a heterozygous yellow-seed plant (Yy), the probability of forming a "Y" gamete is blank. The probability of forming
hram777 [196]

Answer:

<em>The probability of forming a "Y" gamete is 50%. The probability of forming a "y" gamete is 50%.</em>

Explanation:

Mendel was an Austrian monk whose findings led to make the foundation of genetics. Hence, Mendel is known as the father of genetics. He formulated two laws based on the researches he made:

  • Law of segregation
  • Law of independent assortment

According to the law of segregation, alleles segregate independently at the time of gamete formation. There is an equal chance for a gamete to carry the dominant or the recessive allele.

Hence, the probability of a gamete carrying a 'Y' or a 'y" allele will be 50% each.

ehidna [41]
<span>Depletion of the ozone layer. Choloroflourocarbon (CFCS) are dangerous because of their destructive reaction with Ozone particles, which provide the Earth with a protective layer or shield against UV radiation. Depletion of the ozone layer begins when when CFC gets into the stratosphere. Sunlight breaks up cfcs releasing Chlorine Atom. Chlorine atoms in turn react with Ozone, starting a chemical cycle that destroys the ozone layer in that area. Once the ozone layer is depleted, there's nothing holding back the harmful UVB wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere causing havoc on plants and animals.</span>

Consider the regulation of galactose metabolism through GAL4. Which of the following would result from a mutation that allowed G
evablogger [386]

Answer: Option C.

GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.

Explanation:

Gal 3, Gal 80 and Gal 4 are form of proteins which participate in metabolism. They constitute a galactose-responsive switch for the GAL genes When galactose is absent, Gal 80 bind to Gal 4, masking the Gal4AD prevent gene transcription and prevents Gal4-mediated promoter activation

QUESTION 3
ExtremeBDS [4]

Answer:

Q3 the right answer is  A) the aluminium pot

QUESTION 4   B. A lake full of water ( also depends on volume and mass of water)

Explanation:

Q3. the specific heat capacity is the amount of heat one gram of substance absorb or release to change temperature by one degree centigrade.

The aluminum  heats faster than the water because it requires less energy to heat it up.

but its also have the radiates/conducts away all of its heat so rapidly that it cools off much faster than anything else.

Q4.

If a swimming pool and lake full of water, both full of water at the same temperature were subjected to the same input of heat energy, the lake  would certainly rise in temperature more quickly than the swimming pool. The heat capacity of an object depends both on its mass and its chemical composition. Because of its much larger mass, the lake full  of water has a larger heat capacity than the swimming pool full of water.
