All isotopes of hydrogen will always contain one proton, as a change in the amount of protons will change the substance. Assuming all isotopes aren’t ions and therefore don’t have a charge, then each of these isotopes has one electron. The only difference between them is the amount of neutrons to account for the different atomic masses.
H1
one proton
one electron
zero neutrons
H2
one proton
one electron
one neutron
H3
one proton
one electron
two neutron
C. Deoxyribose sugar because the phospahte group, the nitrogen base, and ribose sugar is needed for ATP.
Answer:
The correct answer will be- endoplasmic reticulum
Explanation:
Plasmodesmata are the cytoplasmic bridges spanning in the cell walls of the plant cell which link the cytoplasm of the adjacent cells. The plasmodesmata play an important role in the plants as they allow the inter-cellular connections between the cells.
The plasmodesmata are derived from the juxtaposed endoplasmic reticulum which forms the axial or the central portion of the plasmodesmata and allows the transport of molecules between two cells.
Thus, the endoplasmic reticulum is the correct answer.
Answer:
Challenge : Competition form other species.
Success : Adaptation and colonisation.
Explanation:
- Challenges like adapting to the new environment and different climatic zones and handle other potential threats like predators as snakes, birds, and others. Their potential to find food and sustain themselves will be a challenge.
- Success factors include their ability to adapt and develop a sense of the different environment and through genetic mutation and natural selection they can develop and grow in numbers.
The term that describes the sheep in this scenario is prey, consumer and primary consumer.
A. Prey
B. Consumer
C. Primary consumers
<u>Explanation:</u>
It is given here that the sheep graze on the grass. Thus sheep is a consumer. When we get into the details of trophic levels in the ecosystem we can understand that autotrophs are the producers of an ecosystem. The organisms that feed on autotrophs are primary consumers.
Here grass is the producer and sheep is the primary consumer since it feeds on the grass. It is also given here that the ranchers have to keep the sheep away from predators. This makes the sheep a prey too. The animals that feed on primary consumers are called secondary consumers.
