Clams that are native to China are living in the San Francisco bay. How can these clams damage the bay ecosystem?​

Answers

Answer 1

Answer:

Marine Invasive Species are animals or algae that have been translocated from their native region to California marine and estuarine waters. Invasive species are also called introduced, exotic, alien, nonindigenous or non-native.The introduction of NIS can cause harm to the ecosystem by displacing native species, becoming a human health dangerby introducing new diseases, or cause economic havoc on commercial, agricultural, or recreational activities by clogging waterways, and impacting navigation and recreation.

A prime example of the harm an invasive species can cause is Caulerpa taxifolia, also known as Killer Algae, a strain of green seaweed believed to be released from an aquarium directly into a water body or through a storm drain. The Killer Algae forms a dense carpet on any surface including rock, sand, and mud displacing native plants and animals, disrupts the natural food chain, and seriously impacting recreational and commercial fisheries.

Although Caulerpa was successfully eradicated from California marine waters, few eradications have been attempted due to perceived challenges and high cost (over $7M was expended in the case of Caulerpa).

Number of Invasive Species Statewide

The map below shows that all major harbor areas and Bays in California have received significant NIS introductions. San Francisco Bay has the highest number of non-native species, followed by the Ports of Los Angeles/Long Beach. San Francisco Bay is a hotspot for invasions because it has high recreational boating and commercial shipping traffic, a history of oyster culture, and is adjacent to a highly urbanized area. Our research found that San Francisco Bay is a hub for the spread of NIS to the rest of the West Coast.

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

An eye can be defined as a specialized organ of sight with the capability to receive visual images that are subsequently transduced into neural signals and relayed to the brain for processing and interpretation. Some of the components of the human eye matched with their description are;

1. Aqueous humor: a transparent liquid which is located between the cornea and iris.

2. Ciliary muscles: muscles attached to the lens to change its shape.

3. Cone: a photoreceptor cell which functions best in bright light. It detects color.

How do changes to genes affect the traits of an organism

Answers

Mutations over the years effect the gene of an organism

Changes  to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

What is the significance of the genes or the traits?

Changes in the genes can affect humans in several ways, such as through genetic mutations that result in changes to the regulation of gene expression and result in the addition or loss of entire genes from the organism. Not all of the genetic mutations lead to expressiable changes, but they may change the protein sequence by changing the polypeptide sequence.

Hence, changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

If data for the growth of this bacterial population continued to be recorded, would the data point at 60 hours be above or below 37 million? Support your answer.

Answers

Answer:

Above 37 million

Explanation:

Explanation in picture below

Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Thus, Bacterial population growth occurs geometrically or exponentially: in  each division cycle (generation), one cell produces 2 cells, then 4 cells, then 8 cells, then 16, then 32, etc.

The relationship shows that the average generation time is constant and  the growth rate of the bacterial population is proportional to the number of bacteria at any given time.

This relationship is valid only during the period when the population grows exponentially, ie. in  the logarithmic phase of growth. Therefore, graphs showing the growth of bacterial cultures are plotted as the logarithm of the number of cells.

Thus, Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.

Explanation:

Research has shown that population size and growth are important factors in the emission of greenhouse gases. ... While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.

Answer:

Longitudinal waves are waves that transfer energy parallel to the direction of wave motion.

Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.

Explanation:

First of all, transverse waves are not mechanical waves at all. Longitudinal waves are mechanical waves.

Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. A typical example of longitudinal waves is wave on a spiral spring.

Transverse waves are waves that transfer energy perpendicular to the direction of wave motion. A typical example of a transverse wave is light wave and other electromagnetic waves.

Facilitated diffusion uses ATP to move molecules down the concentration gradient. Diffusion move molecules through the cell membrane from an area of low to high concentration. Active transport uses ATP to move molecules against the concentration gradient. Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Active transport uses ATP to move molecules down the concentration gradient.

Answers

Answer:

Active transport uses ATP to move molecules against the concentration gradient.Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient

Explanation:

Transmembrane proteins, among others, are the channel proteins and the carrier proteins, and they are in charge of substances transport into or out of the cell.

Channel proteins are involved in passive transport, and facilitated diffusion is a kind of passive transport. Facilitated diffusion transport hydrophilic molecules that can not freely move through the membrane. Channel proteins carry them from one side to the other of the membrane, following the electrochemical gradient, so they do not need energy to carry in or out substances. Uncharged molecules´ movement depends on concentration gradients, while ions´ movement depends on an electrochemical gradient.Carrier proteins are involved in active transport. Active transport acts against the electrochemical gradient, so it does need the energy to transport substances. It carries molecules from a low concentration side to a high concentration side. The used energy comes from ATP (Na-K bomb) or the membrane´s electric potential.

Why does the grass look green under sunlight and black under the moonlight?

Answers

Answer: The original colour of grass is green because of photosynthesis. But in terms of reflection, it looks green because the sunlight reflects the green colour off the grass, so we see it as green.

Explanation: Sun appears white, but it is made up of the colors: red, orange, yellow, green, blue, indigo, and violet. When white light hits an object, it absorbs some colors and reflect the others. Grass appears green because it absorbs all the wavelengths except green. Green is reflected off the grass, so we see grass as green. The moon doesn’t have light of its own, the moon lights up because of the sun. So at night, as the light of the sun doesn't reach the grass directly because of the moon, it doesnt reflect any color off the grass, and so our eyes detect grass as black.
