What ecological factors do you think might come into play when deciding how to time a pulse flow?
Answers
Answer:
- Species inhabiting the river and surrounding areas
- Hydraulic characteristics
- Geomorphology dynamic
- Water quality
Explanation:
Presence of different species: Assay the species inhabiting the area of the river corridor. These species include invertebrates, animals such as fishes, amphibians, reptiles, birds, and mammals, and plants living near the shore and on the floodplain. These species might be affected in some portion of their life cycles by the difference in the river pulse flows. Life stages and population dynamics might be considered of importance when timing the pulse flow.
Hydraulic characteristics: Habitat in aquatic systems varies according to the season and the pulse flow. Depth, velocity, substrate, and instream cover might be considered important factors influencing the presence of different species and their development.
Geomorphology: Refers to the shape of the channel and floodplain. These will depend on the stream velocity, sedimentation, depth, among others. The river geomorphology is in constant change, from season to season. This dynamic also affects the shape of the floodplain and riparian zone.
Water quality: Refers to the difference in sediments, suspended elements, available nutrients, dissolved oxygen, and temperature. All of these affect and influence different forms of life and their evolution through the corresponding cycle stages.

Now choose one of the resources used for energy production that you have studied in this lesson. Describe how the way humans use or obtain this resource might impact the natural resource you described in part A. If you don’t think the natural resource in part A is affected, explain why.
Answers
Answer:
HERE
Explanation:
One resource used for energy production that can impact the natural resource of ozone layer depletion is coal. Burning coal releases pollutants like sulfur dioxide, nitrogen oxides, and mercury into the atmosphere, which can contribute to the formation of smog and acid rain. These pollutants can also react with other chemicals in the atmosphere to break down ozone molecules, contributing to the depletion of the ozone layer. So, the way humans use coal as an energy resource can have a negative impact on the ozone layer and the environment.

Draw a flow chart that explains how DNA is used to create an organism. please use the words: DNA, gene, protein, cell, tissue, organ, organism.
Answers
Answer:
Please find the flowchart attached as an image
Explanation:
DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.
PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.

What is DNA transcription?DNA transcription is the process by which genetic information encoded in DNA is converted into RNA molecules. During transcription, the DNA double helix is unwound and one of the strands is used as a template for RNA synthesis. RNA polymerase, an enzyme, moves along the template strand, adding complementary RNA nucleotides to the growing RNA strand. The process continues until the RNA molecule is completed.
The process of transcription is tightly regulated to ensure that genes are expressed at the right time and in the right cells. Transcription factors, regulatory proteins that bind to specific DNA sequences, control the rate and specificity of transcription.
Mutations that disrupt transcription can lead to a variety of diseases, including cancer and genetic disorders.

When exercising routinely, timing the food that you eat around your exercise activities is important and has a significant impact on your energy levels. Carbohydrate intake, in particular, can affect performance, with simple carbohydrates and complex carbohydrates having different ideal times for consumption. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores. Sort the following food items
a. Foods rich in simple carbohydrates.
b. Foods rich in complex carbohydrates.
c. Foods without carbohydrates
Answers
Answer:
(a.) Foods rich in simple carbs- Low fat smoothie and sport drinks with glucose
(b.) Foods rich in complex carbs- whole-wheat pancakes, whole-wheat spaggetti with marinara sauce and brown rice with vegetables
(c.) Food without carbs- grilled salmon and roasted chicken breast
Explanation:
Simple carbs are easy to digest and eaten before a workout, hence the sports drink and low-fat smoothie falls under that category, while complex carbohydrates are hard to digest...think anything with wheat.
In saltwater, the water that surrounds a fish has a higher concentration of dissolved salts than is found in the fish's body cells. Which two methods allow the fish to maintain water balance? A. Pumping out salt through the gills B. Absorbing water into the body by osmosis C. Releasing only a little water in urine D. Taking in salts via food
Answers
The two methods that allow fish to maintain water balance in saltwater are pumping out salt through the gills and absorbing water into the body by osmosis.
In saltwater, the concentration of dissolved salts is higher in the surrounding water than in the fish's body cells. To maintain water balance, fish have developed two main methods:
1. Pumping out salt through the gills: Fish possess specialized cells in their gills that actively pump out excess salts from their bodies. This process helps maintain a lower salt concentration within the fish's body, preventing dehydration and maintaining water balance.
2. Absorbing water into the body by osmosis: Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. Fish have a protective layer of skin that allows water to be absorbed into their bodies while preventing the entry of excessive salts.
By absorbing water through their skin, fish replenish the water lost to the surrounding saltwater, helping to maintain their internal water balance.
These two mechanisms work together to enable fish to survive in saltwater environments. By actively pumping out salts and absorbing water, fish can regulate their internal salt concentration and prevent dehydration, ensuring their overall water balance is maintained.

Answers
Answer: The concentration of sugar in solution D is 35%. Solution D is a hypertonic solution as the solute concentration is more than the potato cell concentration. Therefore, water will move into the cell to equalize the osmotic pressure gradient between the cell and the solution. Hence, strip D will swell.

Transcription of the developmental gene M is influenced by two different proteins: B and H. Studies of single and double mutants generated the following information:
In mutants lacking B, transcription of M does occur
In mutants lacking H, transcription of M does not occur.
In double mutants lacking B and H, transcription of M does occur.
Based on this information, put these genes in order in a developmental pathway. Use arrows and t-bars between the genes as appropriate. Choose the correct identity of each below.
Gene 1 1st Symbol Gene 2 2nd Symbol Outcome
Answers
Answer:
B --I H >> M transcribed
Explanation:
Reverse genetics is a classical approach used in molecular genetics to elucidate gene function in a signaling gene network. This technique consists of producing loss of function mutations in genes of interest in order to analyze their phenotypic effects in the downstream signaling pathway.
In this case, the mutation in B didn't affect the expression of the developmental gene M, together with the other mutant lines, this experiment indicates that B is a downstream suppressor of H (since further experiments show that B plays a role in the signaling pathway). Moreover, the mutation in the gene H affects the expression of M, thereby showing that H acts as a downstream activator of M. Finally, B-H double mutants did neither affect the expression of M, thereby showing that M transcription is dependent of the interaction between B and H.
Knowing that proteins B and H interact with each other, and they influence the expression of the M gene, we can propose the following developmental pathway B gene --| H gene >> M gene
------------------------------
Gene pathways refer to the regulation of genes expression by turning them on and off. Many genes and proteins might be involved in this process, each of them playing significant roles in the signaling pathway.
Available data:
The transcription of gene M depends on proteins H and BIf protein B is lacking, gene M is transcriptedIf protein H is lackin, gene M is not transcriptedIf B and H are lackin, gene M is transcriptedAccording to this information, we can assume that,
The mutation in protein B did not influence the transcription of the gene M because even when B is lacking, the gene is transcripted anyway.
However, we can see that H affected M transcription. The mutation in the H protein influenced the gene transcription.
Mutations in proteins H and B did not influence the transcription of the M gene because, in the absence of both proteins, the gene was expressed.
Probably proteins B and H interact with each other, and this interaction influences the M gene transcription.
The developmental pathway is then as follows,
B gene --| H gene >> M gene

Which organisms can reproduce using the process of fragmentation
Answers
Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.
In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.
Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.
Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms, annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.
Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.
Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.
Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.
Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D
