Answer:
Option 3, Chromatids remain attached to one another until anaphase
Explanation:
Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes.
Hence, option 3 is correct
The deer eats grass, the percentage of energy will the deer acquire from the grass will be dependent on the food chain then the accurate solution is 10 percent.
- In a food chain, the simplest 10 percent of the strength is transferred from one trophic stage to another.
- The grass is the manufacturer and the deer is the number one consumer, so, whilst the deer eats the grass, it acquires 10 percent of the entire strength of the grass. Rest strength is dissipated withinside the surroundings thru the metabolic tactics taking location withinside the grass.
<h3>What is the position of deer in the food chain?</h3>
The 2nd trophic stage includes organisms that consume the producers. These are known as number one purchasers or herbivores. Deer, turtles, and plenty of varieties of birds are herbivores. Secondary purchasers consume the herbivore.
Thus it is clear that 10 percent of energy will the deer acquire from the grass.

Answer:
primary
Explanation:
Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.
The right answer to this question is option D. Carotenoids are categorized into two major divisions: carotenes and beta carotenes
First, let's check option A, it says that the carotenoids include red, orange and yellow pigments, that's true, we can check that on lab for example, a vegetable that can be mentioned here are carrots, it has lots of this and it's very healthy too, and remember, there isn't a single animal that can produce carotenoids, so they need to grab it from nature.
The second option, B. says that sometimes carotenoids are sometimes called as acessory pigments, that's true too, some studies consider them acessory pigments, so, they're not alone there, there are different kinds of pigments that can be on that plant, and they're also very important for the animals. Option C refers to beta carotene as the most abundant carotene in plants, that's true too, we can also find other kinds of carotenoids on plants, but this one as it's seen in lab, is the most common one. The last one, D, isn't true, the two major divisions are: Xanthophylls and Carotenoids, beta carotenoids are a type of carotenoids, not a different group.
Well our bodies get the energy they need from food through metabolism. So the answer is food
