Answer:
fruit, the fleshy or dry ripened ovary of a flowering plant, enclosing the seed or seeds. Thus, apricots, bananas, and grapes, as well as bean pods, corn grains, tomatoes, cucumbers, and (in their shells) acorns and almonds, are all technically fruits.
Explanation:
A botanical fruit would have at least one seed and grow from the flower of the plant. With this definition in mind, cucumbers are classified as fruit because they contain tiny seeds in the middle and grow from the flower of the cucumber plant. Drupe - has fleshy fruit and a single seed with a hard endocarp eg peaches, coconut and olives.
Berry - has many seeds eg tomatoes, peppers and cucumber but not strawberries!
Aggregate fruit - develop from one flower with many pistils eg strawberries.
Legumes - split along two sides eg beans, peas.

Have the discoveries of the extrasolar planetary systems confirmed the nebular hypothesis predictions?
The discoveries of the extrasolar planetary systems can confirm nebular hypothesis predictions, as the nebular hypothesis said that there are still remaining planets present that are undiscovered.
What is a nebular hypothesis?This hypothesis states that the Sun and all of the planets in our Solar System were originally part of a vast cloud of molecular gas and dust that collapsed some 4.57 billion years ago due to some terrible event.
Therefore, the nebular hypothesis predicted that there are still additional planets present that have not yet been identified, and the findings of the extrasolar planetary systems can corroborate those predictions.

In the graph above (SEE ATTACHED), which letter represents the activation energy (EA) of a catalyzed reaction and why?
ANSWER: (SEE ATTACHED)
In the graph shown above, a letter which represents the activation energy (EA) of a catalyzed reaction is: A. Y; the activation energy (EA) is reduced in a catalyzed reaction.
What is an enzyme?An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction such as the break down of food by the digestive system, especially by lowering the activation energy of its chemical reactants.
Generally, an enzyme speeds up or catalyzes the rate of a chemical reaction by lowering its activation energy.
What is an activation energy?In Science, an activation energy can be defined as the minimum quantity of energy that must be provided for reacting chemical elements or molecules, in order to enable them undergo a chemical reaction.
This ultimately implies that, the rate of any chemical reaction would be faster when its activation energy is lowered, decreased, or reduced.
Based on the graph shown in the image above, we can infer and logically deduce that Y is a letter which represents the activation energy (EA) of a catalyzed reaction because the activation energy (EA) is generally reduced in any catalyzed reaction.

Which of the following processes releases carbon into the air? (5 points)
Answer:
Explanation:
Combustion of fossil fuels: Burning coal, oil, and natural gas to produce energy releases carbon dioxide (CO2) into the atmosphere.
Other processes that can release carbon into the air include:
Deforestation: Trees absorb carbon dioxide through photosynthesis, and cutting down forests can release the carbon stored in the trees and soil.
Volcanic activity: Volcanic eruptions can release carbon dioxide and other greenhouse gases into the atmosphere.
Decomposition: When organic matter such as plants, animals, and other living organisms decompose, they release carbon dioxide and other gases into the atmosphere.
Ocean outgassing: The ocean absorbs and releases carbon dioxide as part of its natural cycles, and some of this carbon can be released into the air.
It's important to note that while some of these processes are natural, human activities such as burning fossil fuels and deforestation have significantly increased the amount of carbon dioxide in the atmosphere, leading to climate change.
one of the proerties on enzyme activity is that each enzyme acts in a specific medium true or false?
Answer:
Each enzyme acts at a specific temperature, specific pH, and on a specific substrate (food upon which the enzymes act). For example, salivary amylase (found in the saliva of the mouth) works best at neutral pH, whereas gastric enzymes work best in acidic medium, and the intestinal or pancreatic enzymes work best in basic medium.
Explanation:
Which of the following would provide best evidence that the trait is dominant
Answer:
In genetics, a trait is considered dominant when it is expressed in the phenotype of a heterozygous individual, meaning that it only requires one copy of the dominant allele to be expressed. On the other hand, a recessive trait is only expressed when both copies of the allele are present in the individual's genotype.
To provide the best evidence that a trait is dominant, we would need to observe the trait in the phenotype of all individuals who carry at least one copy of the dominant allele. This means that if an individual has one dominant allele and one recessive allele, they should still show the dominant trait in their phenotype.
In practice, this could be demonstrated through a series of crosses between individuals with known genotypes. If the offspring of a cross between a homozygous dominant individual and a heterozygous individual all show the dominant trait, this would be strong evidence that the trait is dominant. Similarly, if the offspring of a cross between two heterozygous individuals show the dominant trait in a 3:1 ratio, this would also support the idea that the trait is dominant.
In general, the best evidence for a dominant trait would be consistent expression of the trait in the phenotype of individuals who carry at least one copy of the dominant allele. This can be observed through controlled breeding experiments and statistical analysis of the resulting offspring.

How do you think magma and sediment form?
Answer:
Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Magma forms from the partial melting of mantle rocks. These little blobs of melt migrate upward and coalesce into larger volumes that continue to move upward. As they rise, gas molecules in the magma come out of solution and form bubbles and as the bubbles rise they expand (as outside pressure gets lower).

2. Explain how the different types of planets in the solar system illustrates how the density was distributed throughout
the period of planetary formation.
Different types of planets in the solar system illustrate density distribution throughout the period of planetary formation. Mercury, Venus, Earth and Mars are dense whereas Jupiter, Saturn, Uranus and Neptune are less dense.
The Solar System consists of the Sun with eight planets orbiting it. The four inner planets are those closest to the Sun .They are Mercury, Venus, Earth, and Mars. They are smaller and composed of metals and rocks and hence are dense. The four outer planets are Jupiter, Saturn, Uranus, and Neptune. They are larger and mostly made of gases, so the overall density is low A planet's density is related to its composition.
Mercury is the smallest in size. Earth and Venus are almost the same size, whereas Mars is about half their size.
According to the nebular hypothesis, Uranus and Neptune exist in a region where the density of the solar nebula is reduced and longer orbital times is longer . The two are thought to have formed in orbits near Jupiter and Saturn, where more material was available, and to have migrated outward to their current positions over hundreds of millions of years.

The recessive gene is only expressed if there are two alleles. A recessive allel will only produce a phenotype if there is no dominant allel present. Recessive alleles are represented by lowercase letters, while dominant allels are uppercase.
Plant stems contain cells with specific types of compounds, such as lignin, that provide strength to the stem. Which of the following does a role of plants stems in a process that occurs in plants?
The xylem and phloem does the role of plant stems in a process that occurs in plants.
What are the roles of xylem and phloem in plants?Plant stems play a crucial role in the transport of water, nutrients, and sugars throughout the plant and this transport occurs through two specialized tissue types found in the stem: xylem and phloem.
Xylem is responsible for the upward movement of water and dissolved minerals from the roots to the rest of the plant. It consists of specialized cells called tracheids and vessel elements that are interconnected, forming tubes or vessels.
Phloem facilitates the downward movement of sugars and other organic compounds, such as hormones, from the leaves to other parts of the plant. It consists of sieve tube elements and companion cells.

Explain the difference between inter-cooperation and intra-cooperation between species.
Answer:
In evolution, co-operation is the process where groups of organisms work or act together for common or mutual benefits. It is commonly defined as any adaptation that has evolved, at least in part, to increase the reproductive success of the actor's social partners. For example, territorial choruses by male lions discourage intruders and are likely to benefit all contributors.
This process contrasts with intragroup competition where individuals work against each other for selfish reasons. Cooperation exists not only in humans but in other animals as well. The diversity of taxa that exhibits cooperation is quite large, ranging from zebra herds to pied babblers to African elephants. Many animal and plant species cooperate with both members of their own species and with members of other species.
