Explain why Calix's cells having more DNA than a normal cat meant point mutation was not the cause.
Answers
Mutation is the reason for the more DNA in Calix's cells.
Calix's cells having more DNA than a normal cat because of the mutation in the genes. There is no other way through which DNA in a gene increases. This increase in DNA from a normal condition leads to cancer and other disorders.
Mutation occurs in an organism when they are exposed to radiation which damaged the DNA of that organism so we can conclude that mutation is the reason for the more DNA in Calix's cells.

Calix's cells having more DNA than a normal cat meant point mutation was not the cause but it happens due to chromosome number.
These Calix's cats are taken into consideration by all ladies  due to the fact they have got X chromosomes. As not anything extra than an ensuing or outcome, second in time genetic mutations, which appear to be preferred substitutions that affect the duration of the swapping or exchange meant of a nucleotide collection with simply any other nucleotides, ensue in an extra quantity of DNA for the duration of the Calix's cats.

A Three-leaf clover is dominant (T) to four leaves (t). What is the probability of an offspring having 4 leaves when you cross a heterozygous clover with a four-leaf clover?
O 25%
O 50%
O 75%
O 0%
Answers
Answer:
%50
Explanation:
Heterozygous = 2 different alleles (Tt)
4 leaf clover = 2 recessive alleles (tt)
T is dominant over t, so with the combination of Tt three leaves are expressed, rather than four leaves
For a recessive trait (four leaves) to show 2 recessive alleles are needed
To find the percentage of the offspring to have four leaves a punnet square should be created
To find the percentage divide the number of four leaf offering with 4 and multiply by 100
2÷4×100=50
= 50%

What is cosmic microwave background radiation?According to the theory of the Big Bang, the cosmic microwave background is an electromagnetic radiation that is a relic from an earlier stage in the development of the universe. This radiation is also known as "relic radiation." The Cosmic Microwave Background (CMB) is the weak radiation that permeates all of space.
One of the primary confirmations of the Big Bang is thought to be its discovery and thorough studies of its attributes. The cosmic background radiation was accidentally discovered in 1965, which shows that the early cosmos was dominated by a radiation field with extraordinarily high temperatures and pressure.

Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity in the neighborhood you chose.
Answers
Hello. You have not shown the neighborhoods to which the question relates, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The best way to reduce spending on carbon dioxide and increase biodiversity in a neighborhood is to provide tree planting through urban afforestation. A well-wooded neighborhood, it has a lower concentration of carbon dioxide because the plants absorb this gas releasing oxygen in place. In addition, some animals such as birds would attract them, in addition to promoting fruit and shade for the neighborhood.
Answer:
The most ideal way to lessen spending on carbon dioxide and increment biodiversity in an area is to give tree establishing through metropolitan afforestation. A well-lush area, it has a lower centralization of carbon dioxide in light of the fact that the plants assimilate this gas delivering oxygen set up. Likewise, a few creatures, for example, birds would draw in them, as well as advancing products of the soil for the area.

An elementary school science teacher decided to liven up the classroom with a salt-water aquarium. Knowing that salt-water aquaria can be quite a hassle, the teacher proceeded stepwise. First, the teacher conditioned the water. Next, the teacher decided to stock the tank with various marine invertebrates, including a polychaete, a siliceous sponge, several bivalves, a shrimp, several sea anemones of different types, a colonial hydra, a few coral species, an ectoproct, a sea star, and several gastropod varieties. Lastly, some vertebrates - a parrotfish and a clownfish - were added. She arranged for daily feedings of copepods and feeder fish.
The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that by providing live copepods (2 mm long) and feeder fish (2 cm long) the dietary needs of all of the organisms would be satisfied. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)?
1. sponges
2. coral animals
3. bivalves
4. sea stars
5. shrimp
Answers
Answer:
sponges
Explanation:
because sponges need photosynthesis in order manufacture their food
The organisms namely sponges and coral animals are most likely to starve to death in the lack of photosynthetic endosymbionts. The correct option is 1 and 2.
What are endosymbionts?Endosymbionts are organisms that live in close proximity to another cell or organism.
As sponges are predominantly filter feeders, consuming detritus, plankton, viruses, and bacteria. They also absorb nutrient solution from water directly through their pinacocyte cells.
Due to the lack of photosynthetic endosymbionts the organisms namely sponges and coral animals are most likely to starve.
Thus, the correct option is 1 and 2.

Birds help take care of each other's young to increase their chances of survival, and the behavior is passed on to offspring.
What is an adaptive social behavior?Adaptive social behavior refers to actions or behaviors exhibited by individuals or groups that enhance their survival or reproductive success. In this case, the birds engage in cooperative parenting, where individuals assist in raising the offspring of others within their social group.
By providing care to the young of other birds, they increase the chances of those offspring surviving and passing on their genes. This behavior benefits the overall reproductive success of the group and is likely to be passed on to future generations, as it contributes to the survival and well-being of the species.
