Why the Chimpanzee's diploid number is 24 instead of 48.

I am not sure if the following table supposes me to write 2 (N) on here...

Thank you very much

Answers

Answer:

It has 24 pairs and 48 number of chromosomes.

Explanation:

The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.

How are ferns, gymnosperms, and angiosperms alike? They are all vascular plants. They depend on water for fertilization. They all produce seeds. Reproduction depends on birds, bees, and other animals.

Answers

Answer:

The correct answer is ''They are all vascular plants''.

Explanation:

Vascular plants or tracheophytes are those organisms of a more evolved plant nature, they are those that have leaves, stem and roots and that have a vascular system formed by conducting vessels. Ferns are pteridophytic vascular plants, they do not produce flowers or seeds and are mostly herbaceous. All those vascular plants that have seeds but do not have flowers are called gymnosperms. The seeds are not covered or protected by an ovary, so they appear visible on the leaves or other parts of the plant. Angiosperms are plants with flowers, whose seeds develop within the ovary, which grows and becomes fruit.

they all vascular plants

Natural selection is sometimes described as "survival of the fittest." Four friends were arguing about what the phrase "survival of the fittest" means. This is what they said: Diya: "I think ‘fit' means bigger and stronger." Ayush: "I think ‘fit' means more likely to reproduce." Daniel: "I think ‘fit' means being able to run faster." Hari: "I think ‘fit' means more intelligent."

Answers

Answer:

Ayush is correct.

Ayush: "I think ‘fit' means more likely to reproduce

Explanation:

Survival of the fittest simply means when organisms living in an environment develop traits or characteristics that help them to fully adapt to the environmental conditions and are able to survive, reproduce and pass on traits to their next generations. It's an indication that the organisms posses some characteristics that can help them to survive and reproduce in unfavorable environmental conditions.

Changes in ____ result in a change in protein structure which alters the ____-type of the organism and MIGHT increase _____.

Answers

Answer:

DNA, genotype and resistance.

Explanation:

Change in DNA of an organism results in a change in the shape and structure of protein because DNA has the codes of instructions on the basis of which ribosomes synthesis proteins for the cell. This change occurs due to mutation in the DNA sequence that causes change in protein. Due to this mutation, the genotype of an organism changes and might increases its resistance that leads to its survival in that environment so we can say that mutation has good effects on the organisms.

Everything in the universe was created when the Big Bang occurred and the universe is expanding

Everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

What is Big Bang Theory ?

The Big Bang theory is an attempt to explain what happened at the beginning of our universe. Major discoveries in Astronomy and Physics have explained that our universe actually had a beginning. Before that moment there was nothing and after that jump there was something  which is our universe.

According to the widely known theory, our universe sprang into existence as "singularity" which goes back around 13.7 billion years ago. Singularities are basically zones which flout our knowledge of physics. They are assumed to be present at the core of "black holes."

Black holes are regions of enormous gravitational pressure. The pressure is assumed to be so extreme that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of interminable density are called "singularities."

Thus, everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).
