What’s the differences between the three main classes of sponges.
Answer: There are three classes. These classes include Calcerea, Desmospongia, and Hexactinellida. They are divided into these classes based mostly on the composition of their spicules and skeletal fibers. (spicules are rod-shaped cellular projections that make up the skeleton of sponges) hope this helps!

Define the term hominin.
Answer:
a primate of a taxonomic tribe ( Hominini ), which comprises those species regarded as human, directly ancestral to humans, or very closely related to humans.
I hope it helps
Thank U
[tex]\red{Answer:-}[/tex]
✭The Hominini, or hominins, form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan (Chimpanzees and Bonobos), but excludes the genus Gorilla (gorillas).
✭The term was originally introduced by John Edward Gray (1824), long before any details on the speciation of Pan and Homo were known. Gray's tribe Hominini by definition includes both Pan and Homo. This definition is still adhered to in the proposal by Mann and Weiss (1996), which divides Hominini into three subtribes, Panina (containing Pan), Hominina ("homininans", containing Homo "humans"), and Australopithecina (containing several extinct "australopithecine" genera).

In the United States, alcoholic beverages that are sold in stores display a government warning stating that pregnant women should not drink alcoholic beverages. This is because
it prevents cleavage division from occurring, so a zygote cannot become a blastocyst.
if a woman drinks alcohol while she is pregnant, she may not be able to ovulate again after childbirth.
studies have proven that alcohol consumption causes long-lasting disorders in the fetus.
the science of chemistry has shown that alcohol is a reactive substance that may interfere with the mother’s food digestion.

In the early 1900s Germany geologist alfred wegener began to question how the structure of Earth formed over time he proposed the theory of continental drift to suggest that all continents were once connected and have drifted to their current location over time. What was the main reason that wegener theory received a lot of radical from the scientific community
Answer:
He did not give a method on how the continents moved
Explanation:
In 1912, Alfred Wegener proposed the idea that the continents are slowly drifting around the Earth. This hypothesis was known as the continental drift. Wegener proposed that the Earth rotation might have been the cause for which the continents move to separate from each other. However, nowadays it is well-known that continents are landmasses localized on tectonic plates that move and interact with each other (and it is referred to as plate tectonics).

Precipitation is one of the main processes involved in the water cycle. It involves the formation of water falling to the ground from clouds and transforming into either rain, snow, sleet, or hail. Which of the following properties of water can be used to explain why when water falls from clouds it is able to form a rain drop? *
A. cohesive ability
B. universal solvent
C. expansion upon freezing
D. moderation of temperature
Answer: A
Explanation: Hydrogen bonds between the water molecules on the liquid surface are relatively strong and pull on each other more than air molecules. This bond strength results in surface tension that tends to minimize the liquid surface area and produce a spherical raindrop.
Precipitation is the one of the main processes in the water cycle. It involves the formation of clouds and transforming into either rain, snow, sleet, or hail. This is possible due to the property of cohesive ability of water molecules. Thus, the correct option is A.
What is Precipitation?
Precipitation is one of the main processes involved in the water cycle. It is the liquid or frozen water which forms into the atmosphere and falls back to the Earth in the form of rain, sleet, snow, or hail. It comes in many different forms. Along with the evaporation and condensation of water, precipitation is one of the three major parts of the global water cycle.
Precipitation is achieved by the cohesive ability of the water molecules which explains the formation of clouds and rain drops. Cohesive forces are responsible for binding the compounds together such as a rain drop containing water molecules.
Therefore, the correct option is A.

The fish in the first bowl couldn't have baby after baby after baby forever. The bowl filled up with fish and many fish died. A bowl this size can only keep three fish alive. What is it called when an area/home/ecosystem has a limit to the number of living things that can live there?
Answer: Carrying capacity
Explanation:
The carrying capacity can be defined as the ability of an ecosystem to sustain a particular number of members of the population of species in terms of availing resources for survival.
According to the given situation, the fish bowl is an ecosystem which can only sustain a particular number of fishes. Thus, the increase in the population of baby fishes was not supported by the fish bowl.

Essay on atoms 70 words
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.

And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time.

7. What happens during mitosis?
(a) The nucleus of the cell divides.
(b) The cytoplasm of the cell divides.
(c) The cell divides.
(d) The DNA replicates.
Answer:
(c) The cell divides.
Mitosis is the process in which a cell divides.
Mitosis is one of the two types of cell division. The other type of cell division is Meiosis.
Meiosis takes place in reproductive cells and the cell is divided into two which is further divided into four by Meiosis-II
While in Mitosis the process is somewhat similar, the parent cell divides into two new cells and there is no further division and also the parent cell and the two daughter cell will be the exact same
