Why is it important for gametes to be haploid cells?
Answers
The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.
Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.
Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.
Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.
Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.

Southern Florida has many tropical hardwood hammocks—forest habitats that are warm, wet, and populated with many broad-leaved evergreen trees. Why might a plant native to an ecosystem with a cooler climate do well if introduced to a tropical hardwood hammock? Group of answer choices The trees in the tropical hardwood hammock are better at competing for native resources than the introduced species are. The wet conditions in the tropical hardwood hammock disrupt the life cycle and limit reproduction of the introduced species. Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock. Pollinators and seed carriers that normally increase the population in the cooler climate are lacking in the tropical hardwood hammock.
Answers
Answer:
Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock.
Explanation:
The tropical hardwood hammocks are habitats that act as small ecosystems markedly different from the surrounding environment, and they may be seriously threatened by introduced plant species. In Florida, exotic plants have been introduced into the tropical hardwood hammock habitat, reaching to about 50% of the flora in some areas. The mature hammock of these habitats can generate a shade that maintains a temperature of several degrees cooler compared to their neighboring habitats, and thereby promoting invasion by exotic species.

Answer:
Form hypothesis: Where do you think trees get the nutrients they need to grow?
I think the trees get the nutrients from the soil and sunlight
Predict: Based on your hypothesis, how will the tree population change if ALL other organisms (deer, bears, and mushrooms) are removed from the forest?
I think they will increase dramatically because there is nothing affecting them badly.
Analyze: Remove ALL organisms except trees. Click Advance year a few times and select the DATA tab. Was your prediction correct? Explain what you found.
Yes my hypothesis was correct without the other organisms affecting the trees growth the tree population increased.
Draw conclusions: Substances that contain carbon and are produced by living things are called organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water, carbon dioxide, oxygen, and ammonia, are called inorganic.Some living things, called producers, can produce the organic materials they need (like food) from inorganic matter. All other organisms are consumers; they consume organic matter since they cannot make it themselves.
Do your results show you that trees are producers or consumers? Explain.
Trees are producers because they make it by using the sun's light.
Analyze: Click the FOREST tab. Click the plus (+) button for mushrooms several times. Click Advance year a few times. Select the DATA tab. How did adding mushrooms affect trees?
adding the mushrooms didn’t affect the trees.
Extend: The mushrooms thrived without hurting trees. How could this happen? Try for two possible explanations. Write your ideas in the space below.
The mushrooms are decomposers; they thrive off of dead things including the trees so they do not harm the trees at all.
Explanation:
The trees in the forest controls the flow of water on the land.
When heavy rainfall occurs the trees help in trapping the water in the soil which reduces the chances of flood. These trees also provide habitat as well as food for living organisms that lives in the forests.
The trees get the nutrients they need to grow from the soil with the help of their roots. Decomposers present in the soil feed on dead bodies which turn into nitrogenous substances that is used by the trees for making amino acids.
The tree population increases if all other organisms such deer, bears, and mushrooms are removed from the forest because these organisms feed on the trees so increase occur in the tree population.

Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.
Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

The center of the atom is called the nucleus. The correct option is B.
How is the center of the atom called?The nucleus is the central region of an atom that contains most of its mass.
It is composed of protons and neutrons, which are collectively known as nucleons.
Protons have a positive charge, while neutrons have no charge. Together, protons and neutrons form the nucleus and are responsible for the stability of the atom. Surrounding the nucleus are electrons, which have a negative charge and orbit the nucleus in various energy levels or electron shells. The nucleus is highly dense and compact compared to the electron cloud surrounding it.
