Goldfish 94
1)
The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
2)
Animal cells always have an even number of chromosomes, and plant cells always have an odd number of chromosomes.
3)
The number of chromosomes present in a diploid cell doubles for each generation because there are two parents.

The diagrams below represent the fossils of shellfish in four hypothetical cross sections of a canyon. The top layers are the
youngest layers, and the bottom layers are the oldest
Which cross section could be used as evidence that, over time, a circular shellfish descended from a hexagonal shellfish?
1
2
3
Answer:
The answer is number 4
Explanation:
Cross section 4 contains evidence that a transition from a hexagonal shellfish to a more a rectangular shellfish and then to a circular shellfish may have occurred. These changes would have been gradual, as shown by the position of the fossils in each layer of the canyon.
Although the evidence provided by cross section 4 is strong, more research would be needed to prove a connection among the shellfish in the canyon, such as morphological or
The cross-section in diagram 4 could be used as evidence that, over time, a circular shellfish descended from a hexagonal shellfish. Hence, option D is correct.
What are fossils?Fossils are the remains or traces of ancient living organisms that have been preserved in sedimentary rocks or other materials over long periods of time. Fossils can include bones, teeth, shells, imprints, or other parts of plants and animals that have been mineralized, or turned into rock, over millions of years.
They are important clues to the history of life on Earth, providing evidence of the evolution of different species and the environmental conditions that existed in the past.
Fossils can be studied by paleontologists to learn more about the biology and ecology of ancient organisms, as well as to understand how the Earth's ecosystems have changed over time. Hence, option D is correct.

What do lungs, a plant leaf, and our digestive system have in common?
Answer:
blood capillaries
but my answer i think that they all take in stuff and release something
plant- take is carbon dioxide and gives out oxygen
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Digestive system- The digestive system converts the foods we eat into their simplest forms, like glucose The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

These puppies were born in the same litter to the same parents, but they have different traits for the feature of toenail thickness. One puppy has thick toenails, one has thin toenails, and the third has medium toenails. How did these puppies end up with toenail thicknesses that are different from one another even though they have the same parents? How did the gene combinations result in the different traits?
Answer:
The parents could have passed down different genes that resulted in different toenail thickness. Another possibility is that one of the parents could have had the dominant gene in some of the puppies and the other parent had the dominant gene in the other puppy.
Explanation:
Let me know if you need any more info :)
Three puppies have different toenails due to the presence of variation in the gene called alleles. This is an example of incomplete dominance. In heterozygous condition, the medium-thick toenail is seen.
What is incomplete dominance?In incomplete dominance, a new character is seen in heterozygous condition. An example is the toenail of puppies. The dominant toenail is represented by T, and the recessive is represented by t. The thick toenail is dominant over the recessive thin toenail.
When a pair of parents Tt are crossed, each produce two gamete such as T and t. From the crossing, three types of offspring are produced: thick ( TT), medium ( Tt) and thin ( tt). The T is not completely dominant over t so they show medium toenail in heterozygous condition.
Though all offspring are from same parents but during gametes formation crossing over and recombination in genes result in the character. The punnett square is explained in the image below.
Hence, due to cross-over and recombination in alleles of genes, different characters are expressed.

five characteristics that all living things share
Answer: All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
Explanation:
The five characteristics that all living organisms share are growth, reproduction, homeostasis, sensitivity, or response to stimuli, and death.
What are living organisms?Living organisms are those organisms that grow, develop, and reproduce. These organisms are divided into different groups and different classes under the taxonomy.
Living organisms are plants animals bacteria and other all organisms that are present. They can be distinguished from nonliving organisms by these three processes. Nonliving organisms cannot grow, reproduce and develop.
On the earth, there are living and nonliving organisms that survive live together and interact with each other nonliving or abiotic factors are important factors for the survival of living organisms
Thus, the five qualities of growth, reproduction, homeostasis, susceptibility to stimuli, and death are shared by all living things.

Describe how population studies can be conducted in a school garden
Answer:
Population studies look at factors for one individual species.
Explanation:
In a garden, there are multiple species of plants growing. You could study different factors of each population, which is just all the individuals of one species in an area. For example, you could study how adding fertilizer affects the growth of tomato plants. To do this, you would have some tomato plants in the garden that have fertilizer added to the soil and some that don't. At the end of a certain period of time, maybe a month, measure the plants, find the average height and compare their growth. This is just one example, but there are lots of different things you could study.
Write down the word and chemical equition of photosynthesis process
Answer:
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Explanation: (credit to Chris Hall in Quora)
On the geological scale, the equation for photosynthesis would be the opposite of combustion/respiration: carbon dioxide and water molecules converted into oxygen and carbohydrate (or hydrocarbon) molecules (one unit of -CH2O- per CO2).
However, such a simplistic formula is extremely misleading, especially when talking about individual plants and algae instead of macro-geo-chemistry. The oxidation of water to oxygen (aka the light reactions) is a separate (but concurrent) process from the reduction of carbon dioxide to carbohydrate or hydrocarbon (aka the dark reactions). See my answer to a similar question here: Chris Hall's answer to Where is the most detailed chemical structure breakdown of all steps of photosynthesis that is reliable?
Some bacteria, algae, and plant cells only perform one half of the typical photosynthetic pathway, either to produce energy without making sugar/hydrocarbon or to assimilate carbon dioxide using stored chemical energy rather than using light directly (similar to chemosynthesis). And some bacteria do photosynthesis without making oxygen at all, using sulfur in the place of oxygen.
In short, photosynthesis should be thought-of as a series of sequential processes and not as a single chemical reaction.

Which nation would be CLOSEST to the command side on this economic
continuum?
O the United States
O the United Kingdom
O France
O North Korea
Answer: D) North Korea
==============================================================
Explanation:
The United States, the United Kingdom, and France are all countries that have capitalistic economies. This means that (for the most part) private industry and the market determines what products are produced and who gets those products. I said "for the most part" because these countries don't follow a purely capitalistic structure. There are some elements of government regulation to ensure that no breakdowns occur. The regulations are also to ensure some level of fairness as well, in addition to preventing things like fraud.
On the other hand, countries like North Korea are known as command economies because the government determines what products are to be made and they determine who gets the products. This means that they set the prices as well to whatever they feel is correct (even if the market may disagree otherwise). The term "communism" is often strongly connected to the term "command economy".
