How does an organism composed of relatively small cells have an advantage over one made of larger cells?
Answers
The surface area-to-volume ratio of a cell diminishes with growth. If the cell were in the form of a cube, the same reasoning would hold true. The plasma membrane won't have enough surface area if the cell enlarges too much to accommodate the volumetric rise in diffusion rate.
In other terms, a cell gets less effective as it develops. One technique to increase efficiency is to divide, while another is to create organelles with specific functions. Smaller single-celled creatures have a high surface-to-volume ratio, which enables them to rely on material and oxygen diffusion into the cell (and waste diffusion out) to survive. This method can be more effective if the objects have a larger volume to surface area ratio. Larger animals need specialized organs (such as the lungs, kidneys, and intestines) that efficiently increase the surface area accessible for exchange activities, as well as a circulatory system to transport materials and heat energy between the organism's surface and core.

Makes predictions about future events: Scientific Hypothesis. Based on observations of natural phenomena: Both Scientific Theory and Scientific Hypothesis. A tentative statement used to guide scientific investigations: Scientific Hypothesis. A well-established, highly reliable explanation: Scientific Theory
A scientific hypothesis is a tentative statement or prediction that can be tested through scientific investigation. It is based on observations of natural phenomena and can make predictions about future events.
A scientific theory, on the other hand, is a well-established and highly reliable explanation supported by a substantial body of evidence. It goes beyond individual observations and hypotheses, providing a comprehensive understanding of a particular phenomenon or set of phenomena.
Both scientific theories and hypotheses can be tested by many independent researchers to ensure the validity and reliability of the findings. Therefore, the term "Can be tested by many independent researchers" applies to both scientific theories and scientific hypotheses.
By categorizing the given terms, we can see that "Makes predictions about future events" corresponds to a scientific hypothesis, "Based on observations of natural phenomena" applies to both scientific theories and scientific hypotheses, "A tentative statement used to guide scientific investigations" refers to a scientific hypothesis, "A well-established, highly reliable explanation" represents a scientific theory, and "Can be tested by many independent researchers" applies to both scientific theories and scientific hypotheses.

the increase of carbon dioxide in the atmosphere has had an effect on the earths climate. What is that effect?
Answers
To explain this usually some sunlight is reflected back into space while some is absorbed by the earth keeping the planet warm. However the increase in greenhouse gases such as carbon dioxide prevent the light from reflecting back into space and this light becomes trapped causing the earth to heat more then it should. You can almost think of the trapped heat from the greenhouse gases as a blanket around the earth trapping the heat in.

what makes you believe that the vegetation has been grown by farmers and has not grown naturally by itself over time
Answers
Organized patterns, irrigation systems, specific crop varieties, and agricultural practices indicate human intervention in vegetation growth, suggesting farming activity.
Determining whether vegetation has been grown by farmers or has grown naturally over time can be assessed by considering various factors. Firstly, the presence of organized patterns or rows of crops suggests intentional cultivation by farmers. The use of irrigation systems, terraces, or other agricultural infrastructure further supports human intervention. Additionally, the selection of specific crop varieties or the presence of non-native plant species may indicate deliberate cultivation. Observation of crop rotation, weeding, and fertilization practices can also provide evidence of human involvement. Historical records or local knowledge of agricultural practices in the area can provide further context. Conversely, natural vegetation tends to exhibit a more random distribution and includes a diverse range of native plant species. Considering these factors collectively can help differentiate between vegetation that has been grown by farmers and vegetation that has naturally grown over time.For more such questions on Vegetation:

Answer:
Explanation:
A gamete is a haploid reproductive cell that fuses with another gamete of opposite strain to form a diploid
zygote.
A zygote is a cell formed by the fusion of the male and female gamete before it undergoes division.
gametes are haploid while a zygote is diploid.
There is exchange of genetic material during sexual reproduction and fusion of gametes. Meiosis is also involved.
The opposite occurs in asexual reproduction and mitosis is involved instead.
Asexual reproduction is common in prokaryotes eg bacteria.

What is the process of Sexual reproduction? Honey Bees
Answers
Answer:
ASEXUAL
female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilised by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally.
SEXUAL
The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.

Answer:
Chunking involves organizing and breaking down information into easier groups to expand capacity. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of short-term memory.
Explanation:
Chunking involves organizing and breaking down information into easier groups to expand capacity. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of short-term memory.
Short-term memory, also known as working memory, is the cognitive system responsible for temporarily holding and manipulating information in the mind to support ongoing cognitive tasks. It has a limited capacity and duration, meaning that it can only hold a certain amount of information for a short period of time.
Chunking involves grouping information into meaningful units, which helps to reduce the number of items that need to be remembered and make it easier to recall them. For example, instead of trying to remember a long list of numbers, such as "8675309," you could group them into smaller chunks like "867-53-09." This results in fewer items to be remembered and a more efficient use of short-term memory.
Rehearsal can also aid in improving short-term memory by keeping the information active in the mind through repetition. This can involve repeating a phone number several times to remember it long enough to dial, or repeating a list of words to remember them for a brief period of time.
In summary, chunking and rehearsal are important techniques for improving short-term memory, which is responsible for temporarily holding and manipulating information in the mind.
What are the gametes that would be formed for the following genotype: Aa?
Answers
Answer:
A and a
Explanation:
GAMETE formation occurs via a process called MEIOSIS. During meiosis, segregation and independent assortment of genes occur. According to Gregor Mendel who proposed the law, the law of segregation states that the alleles of a Gene will separate into gametes. This separation occurs in such a way that only one allele of that gene is found in each gamete.
In this case, an organism with genotype "Aa" will produce gametes that contains the following: A and a. Therefore, the gametes of genotype Aa will be A and a.
