Answer:
as humans population continues to grow, we're cutting down more trees and occupying more lands to suffice the need of citizens, therefore, decreasing the forest biodiversity. Our plastic bags, as well as wastes, are polluting the ocean and eradicating essential species that are required to sustain a balance ecosystem, therefore, decreasing the biodiversity of the ocean that are required to maintain a balance environment.
Human activities have affected in Biodiversity in the ecosystems negatively and such activities include : i) Indiscriminate hunting/fishing ii) Improper waste disposal
Humans in search of food ( meat ) engage in excessive/indiscriminate hunting of endangered species thereby reducing the Biodiversity of animal species present in the wildlife also excessive fishing activities affects the biodiversity of certain species of fishes in our oceans negatively.
When wastes are not properly disposed they degrade the environment and decrease the biodiversity of the ecosystems in the process. the burning of industrial wastes leads to the exposure of certain species to the negative effects of dangerous gases and liquids thereby making the ecosystems to become unbalanced.
Hence we can conclude that some of the human activities impacting biodiversity in ecosystems around the world include : Indiscriminate hunting/fishing and Improper waste disposal

Explanation:
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.

using what have you learnt about the effect of concentration gradient and surface area to volume ratio, explain the adaptations of a leaf for photosynthesis
Answers
Answer:
thanks
Explanation:
Leaves are adapted for photosynthesis and gaseous exchange.
They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
When water evaporates from the leaves, resulting in more water being drawn up from the roots, it is called transpiration.
To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss.
Leaves enable photosynthesis to occur. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.
Plants have two different types of 'transport' tissue, xylem and phloem. These specialised tissues move substances in and around the plant.
5 The theory of plate tectonics was, at first, rejected by most scientists. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. What is responsible for the change in how scientists think about plate tectonics? A New evidence was discovered that made scientists revise their ideas. B. Tectonic plates have begun to move faster and faster over time. C There are more people studying science now than in the past. D Scientists can now travel underneath the plates and observe their motion.
Answers
Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).
What is Tectonic Plates?
Tectonic plates are also known as lithospheric plates. It is a massive, irregularly shaped slab of solid rock that is composed of both continental and oceanic lithosphere. The size of the plates varies greatly from a few hundred to thousands of kilometres.
The plates are the largest in the Pacific and Antarctic Oceans. Its thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere.
Earth's rigid surface known as the lithosphere acts as a skin that rests and slides over a semi-molten layer of rock called the asthenosphere. It can break into many different plates because of differences in the density of rock and differences in subsurface heating between one region and the next.
Thus, Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).

This sample of air at 35°C and 60% relative humidity holds ____ grams/cubic meter of water vapor. The same sample of air at 40°C can hold a maximum of 50 grams/cubic meter of water vapor. If the air currently holds 30 grams/cubic meter, then its relative humidity is ____%.
Answers
Answer:
Since a sample of air at 35 ° C and 60% relative humidity holds 26.25 grams / cubic meter of water vapor. The same sample of air at 40 ° C can hold a maximum of 50 grams / cubic meter of water vapor. If the air currently holds 30 grams / cubic meter, then its relative humidity is 60%.
Explanation:
To solve the following question, the following calculations must be performed:
If 40ºC can have a maximum of 50 grams per cubic meter of water vapor, this would imply a total of 100% humidity. Thus, if 35º had 100% humidity, the amount of grams per cubic meter of water vapor would arise from the following calculation:
40 = 50
35 = X
35 x 50/40 = X
1750/40 = X
43.75 = X
Now, if this implies 100% humidity, to determine 60% humidity the following calculation must be carried out:
100 = 43.75
60 = X
60 x 43.75 / 100 = X
2625/100 = X
26.25 = X
Therefore, if with 100% humidity you have 50 grams per cubic meter of water vapor, with 60% humidity you would have 30 grams of water vapor per cubic meter.

Explanation:
The DNA sequence TTT codes for the amino acid lysine. The DNA sequence TTC
also codes for lysine. What can you conclude from this information?
Answers
Answer:
The genetic code is degenerate and therefore mutations may go unnoticed.
Explanation:
Each triplet of nucleotide bases, which is known as a codon, encodes for a specific amino acid during translation. However, a single amino acid may be coded by different codons. It is for that reason that the genetic code is considered to be degenerate. In this case, Lysine amino acid can be encoded by both TTT (UUU in the mRNA) and TTC (UUC) codons, thereby a mutation T>C at the third nucleotide codon position does not affect the resulting protein (i.e., it is a silent mutation).

what three phases of the cell cycle are considered interphase
Answers
Answer:
The cell cycle has three phases that must occur before mitosis, or cell division, happens. These three phases are collectively known as interphase. They are G1, S, and G2. The G stands for gap and the S stands for synthesis.
Explanation:
The three phases of the cell cycle that are considered interphase include G1, S phase and G2.
The cell cycle can be divided into the interphase and mitotic (M) phases.The interphase can in turn be divided into a Growth G1 phase, synthesis (S) phase and Growth G2 phase.The synthesis of the genetic material (DNA) occurs in the S phase, whereas in G1 and G2 the cell synthesizes all materials required to enter into cell division.In conclusion, the three phases of the cell cycle that are considered interphase include G1, S phase and G2.
