<u>Answer:</u> The correct answer is Option A.

<u>Explanation:</u>

Iodine is the 53rd element of the periodic table. The number of electrons present in this element are 53.

The electronic configuration of this element = [Kr]4d^{10}5s^25p^5

As, the electrons are filled in the orbitals having n = 5. So, it is present in Period 5.

And, the number of valence electrons of this element is 7. So, it is present in Group 17.

Hence, the correct answer is Option A.

Which part of a phospholipid is hydrophilic
natka813 [3]

Answer:

nonpolar fatty acid tails

The hydrophobic, or “water-fearing,” part of a phospholipid consists of its long, nonpolar fatty acid tails. The fatty acid tails can easily interact with other nonpolar molecules, but they interact poorly with water.

What evidence supports the LAW OF CONSERVATION OF ENERGY?
photoshop1234 [79]

Answer:

Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).

Explanation:

Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.

During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.

With respect to the law of conservation of energy, it is necessary to consider:

  1. In the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.
  2. Energy in an isolated system does not vary, unless it comes into contact with another system.
  3. The amount of energy that is absorbed and obtained is equivalent.

In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.

Regarding other options:

<em>     1. In photosynthesis, it is not </em><u><em>mechanical energy</em></u><em> that is transformed into chemical energy.</em>

<em>     3. </em><u><em>Oxygen is a product of photosynthesis</em></u><em>, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.</em>

<em>     4. It is true that the </em><u><em>sun gives off light energy that is absorbed by plants</em></u><em>, but it does not explain how this energy is transformed into chemical energy.</em>

in a certain fish, blue scales (BB) and red scales (bb) are codominant. when a fish has the hybrid genotype, it has patchwork of
Lena [83]

Answer:

BB is blue

bb is red

Bb is patchwork

Explanation:

It can't really be codominant since lowercase letters are recessive, and condomance needs 2 dominant alleles of a different types. So really it should be BB for blue, RR for red and BR for patchwork...

The body of tapeworm is segmented but it doesnot belong to phylum annelidai why​
Wewaii [24]

Answer:

look

Explanation:

Flatworms, roundworms, and segmented worms are all invertebrates. Some species of each type of worm are free-living, meaning they are not dependent on another organism.Some are parasitic.

Flatworms belong to phylum Platyhelminthes. They do not have a coelom, respiratory system or a circulatory system.Tapeworms flukes are examples of flatworms.

Roundworms are part of the phylum Nematoda. They are bilaterally symmetrical invertebrates.They have a psuedocoelom. Ascaris lumbricodes is the most common human parasite.

Segmented worms are the most complex animals of these three invertebrates. They are placed in Annelida. Segmented worms have a true coelom, a circulatory system and a digestive system.An earthworm is a segmented worm.
