<h2>Answer:</h2>
Bt corn is a genetically modified organism that contains a gene of bacteria known as Bacillus thuringiensis.
<h3>Explanation:</h3>
- Bt corn is a type of transgenic crop that contains a gene which produces a crystal-like protein which has an insecticidal effect.
- This gene is present in bacteria. This gene is transferred to the plant by the recombinant DNA technology and genetic engineering.
- This bacterium is a soil bacterium which has no side effects on humans.
- Due to use of this technology, the poisonous chemical insecticides are not used in crop production.
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
Anything specific? This is pretty vague.
A brain would be my answer. Or do you mean a characteristic? Then I’d pick maintain homeostasis.
Answer:
Subpolar low. Subpolar lows: semi-permanent cyclone where surface midlatitude southwesterlies converge with the polar northeasterlies. Subpolar lows, the Aleutian low over the North Pacific Ocean and the Icelandic low over the North Atlantic , are well-developed in winter, but weaken or disappear in summer.
Answer:
The blank is SOURCES
Explanation:
Sources of energy can either be RENEWABLE OR NON-RENEWABLE. Renewable sources of energy are those sources which are easy to replenish while non-renewable sources are difficult to replenish after being exhausted.
Biomass, which comes from plants and animals are considered to be SOURCES of renewable energy because they renewable energy because they take time to grow and require careful planning to ensure continued supply. Trees get their biomass from sun energy, which is a renewable source of energy.
