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.

Both natural processes and human activity are causing some of Earth's permanent bodies of ice to melt. If enough of this ice melts, it will add warm freshwater to the northern Atlantic Ocean, where deep water currents start. What effect is this likely to have
Answer:
EFFECTS - : Melting glaciers and icebergs release fresh water and reduce the salinity of the surrounding sea. The seawater also becomes less dense, changing patterns of ocean currents.
Explanation -
MELTING OF ICE AND ADDING WARM FRESH WATER TO NORTH ATLANTIC OCEAN -: As part of the thermohaline circulation (also called the Global Ocean Conveyor), seawater flows through the Atlantic, the normal pattern by which seawater passes to the oceans of the world. Due to variations in water density caused by differences in temperature and salinity, the water in the Global Ocean Conveyor circulates. Colder water is denser than colder water, while salter water is denser than fresh water or less salty water.
Water heated at the Equator flows north to cold high latitudes at the surface of the ocean, where it becomes colder. When it cools, the deep ocean becomes denser and sinks. To take its place, more warm surface water flows in, cools, sinks, and the pattern continues. But this trend may be modified by melting Arctic sea ice.
The influx of freshwater from the melting ice makes seawater less salty and thus less thick at high latitudes as the Planet begins to warm and Arctic sea ice melts. In reality, data shows that over the past few decades, the North Atlantic has already become fresher.
Answer:
Salinity changes in water

How do the components of sugar molecules combine to form proteins and other larger carbon based molecules
-Will give brainliest-
Answer:
The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.

Explain how the structure of saturated fats poses a danger to your health.
Answer:
Saturated fats are long chains of rigid fats.
Explanation:
Saturated fats will raise the cholesterol levels of an individual. Their structure results in deposits of fatty acids within arteries and vastly increases the risk of heart-related disease.

2. The thread-like chromosomes are spread
throughout the nucleus in the form
Answer:
When the cell is not dividing, the genetic material is loosely dispersed throughout the nucleus in a threadlike form called chromatin.
Explanation:
Chromatin is the thread-like chromosomes spread throughout the nucleus.
What are chromatin and its functions?Eukaryotic cells' nuclei include a combination of macromolecules called chromatin, which is made up of DNA, RNA, and protein. Heterochromatin (condensed) and euchromatin are the two types of chromatin. The main proteins that make up chromatin are termed histones, which act as bases for the DNA to wrap around to form the "bead-like" structures known as nucleosomes.Functions of chromatin:DNA packagingTranscription regulationChromatin and DNA repair

Gametes produced by an organism contain a combination of genes from that organism. In every gamete, this combination is
A. the same because it is created from the same DNA
B. the same because chromosomes are copied prior lo melosis
C. different due to DNA replication prior to mitosis
D. different due to independent assortment during meiosis
Answer:
D). different due to independent assortment during meiosis
Explanation:
Gametes that an organism produces accommodates a blend of genes of that organism and in each gamete, this blend or combination is 'distinct and that is due to independent assortment during meiosis.' It implies that the chromosomes pass randomly for isolation of poles during the division of cells at the time of the process of meiosis and this independent segregation causes each gamete to contain a unique combination of genetic code. Thus, option D is the correct answer.

Engineers tasked with building a car bumper need high-quality plastic that is readily available. They found the material polycarbonate, which is long-lasting and not too costly. Which is one technological design criterion they have already met? be available be attractive be durable be safe
Answer:
be durable
Explanation:
From the scenario described the Engineers have met one of the main criteria which is for it to be durable. A design needs to be made with a material that is available, durable, and cheap in order for it to be as efficient as possible while also selling and being profitable. By finding the material polycarbonate they have made sure that the design will be durable as well as cost-efficient since the material is "not too costly". Now if they are able to acquire the material in large quantities then they would have met the availability criteria as well.

In 2003 a disease called SARS was a major concern for health officials. SARS is a very contagious respiratory disease. People were infected by SARS in several countries. Fortunately, health officials worked quickly to get the disease under control before it spread worldwide. Which statement best describes SARS? SARS was an epidemic, but not a pandemic. SARS was a pandemic, but not an epidemic. SARS was both a pandemic and an epidemic. SARS was neither a pandemic nor an epidemic.
Answer:
The correct answer is - SARS was both a pandemic and an epidemic
Explanation:
SARS or Severe acute respiratory syndrome is a viral infection that is first reported inChina in 2003 and caused by a coronavirus. It was moving swiftly continent by continent as an epidemic that was limited to Asia but soon it infected the countries in different continents like North America, South America, Asia, and European countries to become a global epidemic or pandemic.
Thus, the correct answer is - SARS was both a pandemic and an epidemic

How does cognition and biology influence learning?
GREETINGS!
Both Cognition and biology plays role in Conditioning and Learning
Cognitive aspects of learning refer to thinking processes and mental procedures involved in the learning process. Cognitive factors that influence learning range from basic learning processes, such as memorizing facts or information, to higher-level processes, such as understanding, application, analysis and evaluation.
Biological factors also play important role for example Aversion to a particular taste is conditioned only by pairing the taste (a conditioned stimulus) with nausea (an unconditioned stimulus). Generally, taste aversion is developed after ingestion of food that causes nausea, sickness, or vomiting. If taste is paired with other unconditioned stimuli, conditioning doesn’t occur. Another example is Instinctive drift or Instinctual drift. Any behavior is instinctive if it is performed without being based upon prior experience (that is, in the absence of learning), and is therefore an expression of innate biological factors.
