Answer 1

Answer:

C.  primary consumers to secondary consumers.

Explanation:

An eco-system is a set of living and non living organisms living in a certain area where they interact with each other to fulfill their life requirements. One of the every important component of any eco-system is food chain.

What is food chain?

Food chain is a series of events which involves the living organisms and the process of obtaining their food and nutrition from one organism to another.A food chain starts when the autotrophs or producers or plants produce their food through the process of photosynthesis.The next organism of food chain are primary consumers that eat plant based foods. These are called herbivores. For example: rabbit The next sequence organism of food chain are secondary consumers that eat primary consumers. These are called secondary consumers. For example: snakes that eat rabbit.The next sequence organism of food chain are Tertiary consumers that eat secondary consumers.  For example owl which eats snakes.

So based on above information we can say that flow of energy in an eco system is as:

Sun --> Producers --> primary consumers  --> secondary consumers -->Tertiary consumers

Therefore, only option C is correct.

Hope it help!

what would happen if bismuth -208 lost 1 proton and gained 1 neutron?
A. it would become lead -207

B. it would become lead-208

C. it would become bismuth-207

D. It would stay bismuth-208

Answers

he given isotope is bismuth 208. The atomic number of bismuth is 83 therefore the number of protons is 83. When bismuth loses one proton it results in the element lead with only 82 protons. The mass number is the total number of protons and the total number of neutrons. So on losing proton  bismuth becomes lead and on gaining neutron the mass number does not change and remains as 208. Therefore it reduces to lead but the mass number remains the same.

Therefore the answer is B. Bismuth on losing one proton and on gaining a neutron it becomes Lead 208.

The introduction of zebra mussels in the Great Lakes is an example of which type of release? The introduction of zebra mussels in the Great Lakes is an example of release.

Answers

it has been deduced that larval mussels was released to the Great Lakes during the ballast exchange of a cargo ship from the Black Sea.  so it is an example of un-intentional release.


Final answer:

The introduction of zebra mussels in the Great Lakes is an example of an invasive species release via ballast water from ships, which has both economically impacted human infrastructure and dramatically changed the local ecosystem.

Explanation:

The introduction of zebra mussels in the Great Lakes is an example of an invasive species release. This occurred when ships released ballast water into the lakes from their tanks, which were filled in European ports. The water used for ballast, which helps stabilize the ships during transport, contained living organisms including zebra mussels. Once introduced to the Great Lakes, zebra mussels have cost millions in cleanup expenses to maintain water intakes and other structures and have significantly altered the ecology of the ecosystem. They are filter feeders that have improved water clarity, but they also threaten native mollusk populations and have benefited certain fish species like the smallmouth bass.

A person had bread and butter for his breakfast. Trace the changes in the main components of these during its passage through the alimentary canal

Answers

When the bread and butter is in mouth, mechanical digestion starts. The size of the food gets reduced and it mixes with saliva for easy swallowing. The salivary amylase in saliva begins the digestion of starch in the bread. This is the start of chemical digestion. When the undigested bread and butter reached the stomach, lower esophageal sphincter relaxes and allow the chewed food to enter. The gastric secretions containing HCl, acts on the undigested food to produce chime. HCl kill the microorganism on the food and also denatures the protein and later attacked by digestive enzyme pepsin. Pepsin breakdown protein in the bread, butter . Later on gastric lipase begins to digest fat present in butter. Digestion of the starch in bread does not occur in the stomach because the salivary amylase that began chemical digestion in mouth became inactive in the presence of HCl. Further the chime enters the small intestine where bile secreted by the gall bladder emulsifies the fat and break into small globule which helps in fat absorption.

Glucose is a simple carbohydrate that is made up of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. One glucose molecule is approximately four times larger than one water molecule. Glucose molecules enter most body tissues without the use of energy. Which process is most likely used to transport glucose into a muscle cell?

Answers

because a glucose molecule is to large to pass through a cell membrane cells assist glucose diffusion through facilitated diffusion and two types of active transport.

Final answer:

The process of facilitated diffusion is most likely used to transport glucose into muscle cells as it does not use energy and is helped along by specific carrier proteins in the cell membrane.

Explanation:

The process most likely used to transport glucose into a muscle cell is facilitated diffusion. This process involves specific carrier proteins in the cell membrane that bind to glucose to allow its passage into the cell. These proteins are used because, even though glucose is small in nature, the polar hydroxyl groups (-OH) attached to the glucose molecule prevent it from easily passing through the nonpolar lipid bilayer of the cell membrane.

The process does not require energy as facilitated diffusion is a type of passive transport, moving from a higher concentration (outside the cell) to a lower concentration (inside the cell). Thus, glucose can enter most body tissues, including muscle cells, without the use of energy.

Hi there!

The major structure for a neuron is,

D). Axon, cell body, and dendrites.

Hope this helped!~

The major structures of a neuron are the cell body, dendrites, and axon. The cell body contains the nucleus, dendrites extend from the cell body to receive signals, and the axon transmits signals away from the cell body. The correct answer is D. Axon, cell body, dendrites.

The major structures of a neuron include the cell body, dendrites, and axon. The cell body, sometimes referred to as the soma, contains the nucleus and other essential organelles for the neuron's function. Dendrites are extensions that branch off from the cell body receiving signals from other neurons, while the axon is a longer extension that carries nerve impulses away from the cell body to other neurons or muscles. At the end of the axon, axon terminals, or synaptic boutons, allow communication with other cells. The correct answer to the student's question, identifying the major structures for a neuron, would therefore be D. Axon, cell body, and dendrites.

cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants? Explain.

Answers

Final answer:

The parents are likely heterozygotes (Rr x Rr) because the offspring have a roughly 1:1 ratio of dominant (red) to recessive (white) characteristics. This is evident after performing a Punnett square analysis.

Explanation:

The subject question falls under the category of Mendelian genetics. In the cross you mentioned, almost half the offspring produced are of the dominant phenotype (Red flowers), and half are of the recessive phenotype (White flowers). This suggests a cross between parents that are both heterozygotes (Rr), which produces an approximately 1:1 phenotypic ratio in the offspring.

Using a Punnett square, we set up the cross Rr (Red flower parent) x Rr (Red flower parent). This cross yields the following genotypes in the offspring: 1 RR (Homozygous Dominant red), 2 Rr (Heterozygous red), and 1 rr (Homozygous recessive white). As the recessive phenotype can only be expressed in the rr genotype, this is why we see an approximate 1:1 ratio of red to white flowering plants in the offspring.

Explanation:

A biomass is a source of thermal energy. It is obtain from burning of the plant and animal material. The materials include the wood, waste obtain from the agriculture land like straw, animal dung and even from the human waste like sewage waste.

Biomass is an alternate source of energy. As the biomass is a renewable source of energy and the oil can be a fossil fuel like crude oil including petroleum, which is a non-renewable source of energy. The biomass energy can be replenished as the plants and animal material can be replenish by the natural cycles. Their quantity will never deplete in nature and they will remain available for the present as well as for the future generation. Whereas, the quantity of oil may deplete in nature as being a non-renewable resource the oil can only be used once and the used amount will not be recovered in any accessible way.

What are the 3 stages of cellular respiration?

Answers

The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm, the Kreb's Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.

Cellular respiration consists of glycolysis, the Krebs Cycle, and the electron transport chain. These stages work together to convert glucose and other organic molecules into ATP, which cells use as a source of energy for various biochemical processes.

1.Glycolysis: Glycolysis is the first stage of cellular respiration, and it takes place in the cytoplasm of the cell. During glycolysis, a single molecule of glucose is broken down into two molecules of pyruvate.

This process doesn't require oxygen and is therefore considered anaerobic. It yields a small amount of ATP and some molecules of NADH (nicotinamide adenine dinucleotide), which carry high-energy electrons.

2. Krebs Cycle (Citric Acid Cycle): The Krebs Cycle, also known as the citric acid cycle or TCA cycle, occurs in the mitochondria. In this cycle, the two molecules of pyruvate generated in glycolysis are further broken down. This stage is aerobic, meaning it requires oxygen.

For each pyruvate, it produces three molecules of NADH, one molecule of FADH2 (flavin adenine dinucleotide), one molecule of ATP, and carbon dioxide as waste.

3. Electron Transport Chain (ETC): The final stage of cellular respiration is the electron transport chain, which also takes place in the mitochondria. The high-energy electrons carried by NADH and FADH2 from glycolysis and the Krebs Cycle are passed through a series of protein complexes, creating a flow of protons (H+) across the inner mitochondrial membrane. This proton gradient generates a strong electrochemical gradient, and the flow of protons back through the ATP synthase enzyme results in the production of a significant amount of ATP.

A potted plant placed inside a clear, sealed vacuum container with regular water addition and sunlight exposure will likely undergo photosynthesis and grow, assuming all necessary conditions for plant life are maintained.

The question focuses on the growth of a potted plant inside a clear, sealed vacuum container in which water is regularly added, and the plant is exposed to sunlight. Over time, the plant will likely carry out photosynthesis due to the presence of sunlight and water. These conditions typically enable the plant to produce its own food and energy, leading to growth.

Water movement is crucial for plant survival and growth. In most situations, water will move from the soil to the plant due to osmotic pressure, which is determined by the water potential difference between the plant and its environment.
