The pollen would not be able to reach the eggs inside the female cones. Hope it helps you in a kind of way.
The statement “Feeding scrub-jays can lead to starvation of fledgling scrub-jays” is true because if humans feed the birds, they may become reliant on humans and be unable to get their own food, which can lead to starvation and malnutrition
Answer: Contour ploughing
Explanation: The soil conservation can be defined as the techniques that are opted to conserve soil. It is necessary for the soil to be conserved as it is necessary for the growth of plants.
There are various methods that can be used to conserve soil. Contour ploughing is one of them. In this method furrows are made that move left to right to maintain a constant altitude.
This technique reduces the runoff which helps in the soil conservation.
<u>Answer:</u>
<em>The genetic instructions are found in </em><u><em>the nitrogen bases </em></u><em>within the DNA, which is contained in </em><u><em>nucleotide</em></u><em> inside the nucleus of the cells. </em>
<u>Explanation:</u>
Inside nucleotide there are nitrogen bases along with phosphate group and sugar group. The four nitrogen bases are <em>adenine, thymine, guanine and cytosine (ATGC). </em>
These four bases pair up with each other inside the nucleotide. The order in which these bases are placed determines the genetic codes. This passes the instructions and characteristics from the parents to offspring.
Answer:
A gamma-ray, or gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist, and physicist discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation alpha rays and beta rays in ascending order of penetrating power.
Explanation: hope this helps :)
