The best fertilizers for Trevor to use in his growing experiment of marigold is IV: Type of fertilizer, DV: Growth of marigolds and for Control: No fertilizer.
What is the benefit of fertilizer?Fertilizer provides essential nutrients to plants to support their growth and development. These nutrients include nitrogen, phosphorus, and potassium, which are necessary for the growth of roots, stems, leaves, and flowers.
Additionally, fertilizer can improve soil structure, increase water-holding capacity, and provide essential micronutrients that are important for healthy plant growth. The type of fertilizer for Trevor's experiment is Growth of marigolds (Miracle Grow, Scott's fertilizer, no fertilizer) and for control, no fertilizer(all three treatments are compared).

A 68-year-old Asian female presents with mildly achy muscles and joints. The aches seem to “come and go” quite often lasting for several days at a time. Upon examination you take note of a hunch-backed appearance on the patient. An x-ray is performed and showed a significant decrease in bone tissue mass. After further diagnostic testing is performed the patient is diagnosed with Osteoporosis. TAKE NOTE: Osteoblast cells build bone matrix while osteocytes maintain the matrix. Osteoclast cells break down bone matrix and reabsorb the nutrients.
Using your knowledge of the human physiology, which of the following do you predict is a potential cause of the Osteoporosis?
A. Decreased osteoblast activity B. All choices are potential causes
C. Increased osteoclast activity D. Secondary to external factors like drugs/cancers
Osteoporosis causes bone density to decrease due to decreased osteoblast activity, increased osteoclast activity, and external factors like long-term medication. Option B. All choices are potential causes.
What are the factors that promote osteoporosis?
Let us first review what the bone cells are and their functions,
• Osteoprogenitores → in charge of osteocytes production
• Osteocytes → maintain the matrix
• Osteoblasts → Synthesize and secrete osteoid matrix that will later calcify
• Osteoclasts → Phagocytic cells in charge of osseous resorption and bone modulation.
Osteoporosis is a no-symptoms disease -silent- that causes a decrease in the bone mineral and mass density and might change the bone structure.
Osteoporosis weakens the bone until it breaks. So this affection becomes evident when a fracture occurs.
Several factors lead to osteoporosis development. Among them, we can mention,
genetic factors, habits factors (lifestyle),hormonal alterations,drugs/medication
The increased rate of bone resorption is the major mechanism by which osteoporosis occurs. It deteriorates bone structure and decreases bone density.
Bone resorption and deterioration might be caused by
a decrease in osteoblast activity, leading to the decrease in osteoid matrix formation and calcification,an increase in osteoclast activity, enhancing the activity of these phagocytic cells.
Other external factors also increase the probability of developing osteoporosis. Some of them are,
long-term medications (for instance, those used in cancer treatment) excessive alcohol consumption and smokingsedentary lifestylepoor dietAccording to this framework, the potential causes of the Osteoporosis are Decreased osteoblast activity, Increased osteoclast activity, Secondary to external factors like drugs/cancers.
Hence, option B is correct, All choices are potential causes.

which type of inhibitor will achieve saturation point at alower substrate concentration? With a reason
The molecule in question is classified as an enzyme inhibitor because it interferes an enzymatic reaction. There are two types of inhibitors; competitive and noncompetitive inhibitors. Competitive inhibitors bind to the active site of the enzyme and control substrate from binding.
What do competitive and noncompetitive inhibitors do?
The competitive inhibitor binds to the occupied site and prevents the substrate from binding there.
The noncompetitive inhibitor binds to a separate site on the enzyme; it doesn't block substrate binding, but it causes other differences in the enzyme so that it can no extended catalyze the reaction efficiently.

Answer:
homologous
Explanation:
Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.
:)
Forelimbs of cat and arms of human share a similar bone structure, suggesting a common lineage. These type of common structure are said to be homologous structures.
Organs that function differently in different organisms but have some similarities are known as homologous organs. Although the organs are structurally similar, they serve different purposes. One of the arguments used by scientists to support evolution is the existence of homologous organs.
Even though their structures are based on the same five-digit plan, human arms and the front legs of cats serve different purposes.
Therefore, forelimbs of cat and forelimbs of humans are said to be homologous structures.

Pick one of the following genetic variations that have occurred in human evolution. Then pick one of the three causes of genetic variation (meiosis, replication errors, environmental impacts) and make a claim as to why you think that particular cause of genetic variation was the cause of the change. Use supporting research and/or data to support your claim.
- Smaller bodies
- Smaller brains
- Smaller teeth and jaws
Smaller teeth and jaws are due to genetic variation, which occurred by mutations (errors in DNA replication) and were selected to fill a suitable niche.
What is evolution?Evolution is the mechanism of change of one species to adapt given environment, whereas mutations are the raw material for evolution.
In this regard, scientific evidence supports the fact that jaws evolved to become shorter in humans and thus adapt to a pastoral lifestyle.

Can anybody tell me how cell shape affects function? For example if columnar and epithelial cells shapes affect their respective functions?
Answer:
Cell Shape: Large surface area = Function: Absorption/metabolism increases
Explanation:
The large the surface area of a cell allows for more receptors to interact to increase the amount of metabolism that occurs within the cell. The example you provided, columnar and epithelial cells, are found in various locations throughout the body but are most notable found in the intestinal lining of our intestines. The shape of the columnar which is made up of epithelial cells is waved shaped to allow for more surface area within a given location. Consequently, leading to further absorption.
