Answer:
Type of nucleic acid.
Explanation:
Virus may be defined as the organism that can contains both DNA and RNA as their genetic material. Virus acts as non-living outside the host environment and later acts as living organism inside the host.
Some virus that particularly contain DNA as genetic material. Some virus has the ability to transform RNA into the DNA molecule. Some virus contains only RNA as their genetic material and DNA is not involved in their life cycle.
Thus, the correct answer is option (a).
Answer and Explanation:
Invasive species are not native to an ecosystem/environment to which they've been introduced, which can cause disastrous disruptions to various food chains/webs and other native species' populations.
In this case, your cousin is bringing in a plant from overseas, so it clearly will be an invasive plant. You can tell them the following:
- this plant may take over the feeding source of native plants, causing those populations to decrease drastically or possibly even be wiped out
- secondary consumers that had once relied on those native plants for food energy will now have limited resources, competition will increase, and these consumers may begin to die off
- tertiary consumers that consumed these secondary consumers will begin to die off, as well
- this chain reaction will ripple through the entire food chain and food web, and totally disrupt the existing ecosystem
Thus, your cousin shouldn't plant this organism in their backyard and should instead destroy it.
<u>Answer</u>:
Option d. many small changes can create a whole new species
<u>Explanation</u>:
In the natural selection when the animals gets adapted in a better manner, they tends to thrive in and gets the ability to reproduce more which leads to the formation of the new bigger species. It leads to a change when the individual with few characteristic have the survival chance more also the reproductive rate as compared to others individuals in the group and also passes these inheritable genetic traits to the offspring.
A high-interest rate means the opportunity cost to built or buy a house is high it is a possible channel. So when the interest rate is higher, there may be fewer new housing starts. The abstract point-scoring task requires a minimal model that illustrates a plausible causal channel.
4. When you look up to the sky, it appears as a dark circle with halo light at its edges moving across the face of the sun. As it does, depending on the relative position of the person on earth – that determines where they are on the umbra or penumbra of the eclipse, the place becomes a daytime twilight (umbra) or partial twilight (penumbra).
5. A new moon is formed when the moon is in between the sun and the earth. This is converse to the case of a lunar eclipse where the earth is between the sun and moon. In a new moon, the face of the moon that is faced towards the earth is dark because it is not lit by the sun. It is important to note that a solar eclipse is not formed because the moon’s orbit, around the earth, is tilted at an angle.
