If maggots were spontaneously being produced by meat, then??? A) meat in sealed jar would have maggots B) meat in the open jar would have maggots C) meat in both jars would have maggots
Answer:
C
Explanation:
The correct answer would be meat in both jars would have maggots.
If maggots were spontaneously being produced by meat, both of the meat in a sealed and opened jar would have maggots in them. A spontaneous process would happen without any external force. Hence, whether the jar is sealed or otherwise, the spontaneous appearance of maggots in a jar with meat would still happen.
The correct option is C.
How are biodiversity and the cycling of matter
related to maintaining ecosystem services
Answer: biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
Biodiversity and the cycling of matter are related to maintaining ecosystem services because they ensure the functioning and stability of ecosystems, which provide important benefits such as air and water purification, pollination, and climate regulation.
What is biodiversity?Biodiversity refers to the variety of life in an ecosystem, including the variety of species, genetic diversity within species, and the diversity of ecosystems and landscapes.
Biodiversity is essential for the functioning and stability of ecosystems and provides important ecosystem services such as pollination, soil formation and fertility, climate regulation, and disease control. Biodiversity also helps to maintain resilience in the face of environmental change and provides food, fiber, fuel, and medicinal resources for humans. The loss of biodiversity due to human activities is a major environmental concern, and conservation efforts aim to protect and preserve biodiversity for the benefit of current and future generations.

why do chicken eggs grow larger compared to other eggs?
Answer:
Chicken eggs grow larger compared to other eggs due to their relative body sizes.
Explanation:
Egg laying and the size of an egg is relative to the size of the organism. So an ostrich lays a really large egg because it is a larger animal and can handle that size. Whereas a bluebird lays a small egg because it is a small bird.

M phase is known as mitotic phase and cell division occurs in this phase . The re-formation of the nuclear envelope during M-phase of the cell cycle takes place during telophase . The nuclear membrane which disappears during propahse reappears in the telophase . But before it is reformed the nucleus gets reorganised by Decondensation from chromosomes and reassembly of the nuclear lamina .MORE INFO :-______________
⚡ At telophase stage, nuclear membrane vesicles associate with the surface of individual chromosomes and fuse to reform the nuclear membranes, which partially enclose clusters of chromosomes before coalescing to reform the complete nuclear envelope .
Please Help!!! Explain how the Periodic Table of elements is organized. What are the patterns? Trends?
Answer:
They are the alkali metals, alkaline earth metals, transition metals, other metals, metalloids, non-metals, halogens, noble gases and rare earth elements.
The chemical elements in the periodic table are organized from left to right and from top to bottom based on the atomic number.
How is the periodic table of elements is organized?The periodic table of elements also known as the periodic table is an organized alignment of the 118 elements known at present. The arrangement of chemical elements is done from left to right and from top to bottom on the basis of the enhancing atomic number, or the number of protons in the nucleus of an atom that usually coincides with the enhancing atomic mass.
On the periodic table, the horizontal rows are known as periods, in which each period number demonstrates the number of orbitals for the elements in that row.
Thus, the periodic table of elements is organized from left to right and from top to bottom based on the atomic number.

Which explanation correctly describes why it is important for a cell's surface-area-to-volume ratio to not be too small? Radio button Not checked 1 of 4
Answer:
Hello. You did not put the options, but we can say that the execution of mitosis is what makes it important that the proportion between the colume and the cell surface area is not small.
Explanation:
The ratio between the surface area of a cell and the volume is very large and this is essential for mitosis to occur and for all cells in the same tissue to have the same content and the same drum.
If a cell increases ten times its surface area, it will increase its volume a thousand times. This shows that the cell volume has a much larger proportion than the surface. This makes the cell have a fast metabolic rate and needs to absorb many nutrients, in addition to making a strong exchange of gases with the external environment. This absorption of nutrients so intense, is essential for the cell to enter mitosis and generate two equal cells. This is because during the growth phase the cell will increase in volume until the growth limit of its surface area, once this limit is reached, the cell will have to undergo mitosis and will have enough nutrients for the entire process.

Answer:
1.32°F
2.212°F
Explanation:
1.The melting point is the temperature at which a solid turns to a liquid. The melting point at which ice — a solid — turns to water — a liquid — is 32°F (0°C).
2.Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure and elevation.
3.In other words, the water molecules within ice move faster. However, temperature doesn't change as heat is added during a phase change; for example, when the ice melts. During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.

Characteristics of a ant
Answer:
Their bodies are covered with a hard armor called the exoskeleton. Most ants are either red or black in color and length can be anywhere from 1/3" to 1/2". Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae, and powerful jaws.
Explanation:
The ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, and the segmented body; apart from that, it has an antenna, etc.
What are the features of the ants?The ants belong to arthropods, and the arthropods are non chordates. The special feature of the arthropods is that their bodies are segmented into three parts, such as the head, thorax, and abdomen, and they have an exoskeleton similar to that of the ant. Ants are eusocial animals, meaning they live in groups. Different types of ants are present in different geographical locations, and some of them produce toxins that are harmful to other animals.
Hence, the ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, the segmented body, etc.
