Answer:
Homozygous for that gene.
Explanation:
A diploid individual with two identical alleles for a particular gene is said to be homozygous for that gene, but if the individual has different alleles he or she is said to be heterozygous for the gene.
Answer;
-Non-foliated metamorphic rocks
-Metamorphic rocks that don’t have layers are called non-foliated metamorphic rocks.
Explanation;
-Metamorphic rocks are rocks that go through heat and pressure and change form. They can be formed by pressures deep inside the Earth, by tectonic processes such as continental collisions, or when they are heated up by an intrusion of hot molten rock called magma from the Earth's interior.
-Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure, they include rocks such as gneiss, phyllite, schist, and slate.
-On the other hand,Non-foliated metamorphic rocks do not have a layered or banded appearance, they include rocks such as hornfels, marble, quartzite, and novaculite.
Answer:
The correct answer is a. Pseudomonas aeruginosa would be colorless on EMB
Explanation:
Pseudomonas aeruginosa is a gram-positive bacteria that is rod shape. It shows a few nutritional requirements and can even adapt to those conditions in which the other bacteria can be adapt.
It is non-fermentative bacteria so it does not ferment lactose and other carbohydrates. As EMB agar contains lactose and some dye, therefore, the lactose fermenting bacteria ferment the lactose and show good growth and color change.
But as Pseudomonas aeruginosa is a non-fermentative bacteria it does not ferment lactose and does not show any color and forms a colorless colony. Therefore the correct answer is a.
1.The process of leaf color change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
2.The leaves in hot or dry environments may be adapted to reduce transpiration. For example, their stomata may be open at night and close midday. This is the reverse of what usually happens, and it means that the stomata are closet when the rate of transpiration would be greatest.
The correct answer is A.
Oswald Avery applied several biochemical techniques to large cultures of bacteria in order to extract and purify the "transforming principle". Their experiments showed that most probably the "transforming principle" was DNA. One of the observations leading to this conclusion was that enzymes that degrade proteins or RNA (such ribonucleases) had no effect on the "transforming principle". On the contrary, enzymes degrading the DNA destroyed the extract's transforming capacity.
