What is the role of creatine kinase in the myofibril?
Answer:
Creatine kinase (CK) has several functions in cellular energy metabolism. It catalyzes the reversible transfer of high-energy phosphate from ATP to creatine, facilitating storage of energy in the form of phosphocreatine.
The evidence suggests that the myofibrils' creatine kinase is sufficient to maintain typical tension and relaxation, typical Ca sensitivity, and typical kinetic properties.
What is myofibril?On the long axis of the myocytes, groups of myofibrils—long contractile fibers run parallel to one another (long single multinucleated cells that combine to form the muscle).
On the cell's long axis, the myocytes are situated next to one another in parallel.
Creatine, a molecule found in your muscle cells that aids in the production of energy by your muscles, needs a phosphate group added to it by CK.
Creatine becomes the high-energy molecule, phosphocreatine, which your body uses to produce energy, when CK attaches phosphates to it.
According to the research, the myofibrils' creatine kinase is enough to keep their regular kinetic features, like tension and relaxation and Ca sensitivity, in place.
Thus, this is the role of creatine kinase in the myofibril.

Animals can help plants reproduce in a variety of ways. Which behavior can end up being more harmful than helpful?
A. Birds eat berries and seeds, dispersing the seeds in their droppings as they fly.
B. Iguanas and tortoises eat leaves, fruits, and flowers, relying on each as important
seasonal food sources.
C. Insects like bees and butterflies drink nectar, carrying pollen from one flower to
another.
D. Hummingbirds drink the nectar of flowers, and they will defend their territory in
order to secure their food supply.
Answer:
B
Explanation:
The behavior that can end up being more harmful than helpful when it comes to plant reproduction is iguanas and tortoises eating leaves, fruits, and flowers as important food sources.
When plant tissues or organs are removed, it affects the reproductive potential of such plants. Thus, Iguanas and tortoises feeding on plant tissues and organs is quite detrimental to plants and may offer very little to no benefits.
Birds help disperse seeds by feeding on fruits and dropping the seeds along with their feces. Insects like bees help pollinate flowers and hummingbirds help protect plants from certain predators. All these actions help plant reproduction.

Fungi have characteristics that make them similar to both plants and animals. Which characteristic do fungi share with plants but not animals?
·reproduce sexually
·contain nuclei
·have cell walls
·make their own food
Explanation:
·have cell wall
cell wall is present in plant and fungi due to protection
but not in animals due to locomotion mode of life
Fungi have cell walls characteristic which fungi share with plants but not animals, hence option C is correct.
What are the characteristics of fungi?When compared to animals, fungi need prepared organic substances for energy because they are heterotrophic organisms without chloroplasts.
Fungi are eukaryotic organisms, just like plants, and have nuclei in each of their cells. Like plants, fungi lack a cell wall and vacuoles, however, they do have a material called chitin in their cell walls that plants do not. In numerous important respects, fungi are also similar to animals.
Eukaryotic, non-vascular, immobile, heterotrophic creatures are fungi. They could be filamentous or unicellular and spread spores to reproduce. The phenomena of generational alternation are seen in fungi.
Therefore, in comparison to plants, fungi have vacuoles and a cell wall.

The first two steps of cellular respiration provides the raw materials (NADPH and FADH2) for the third process.
CELLULAR RESPIRATION:
Cellular respiration is the process by which living organisms obtain energy (ATP) by breaking down food molecules in their cells. Cellular respiration occurs in three major stages namely: glycolysis, Krebs cycle and electron transport chain. Electron transport chain (ETC) produces the highest amount of ATP (36), however, the products of glycolysis and Kreb cycle are needed for ETC to commence. These products, which are raw materials (electron carriers) for ETC are NADPH and FADH2 molecules. Therefore, the first two steps of cellular respiration provides the raw materials (NADPH and FADH2) for the third process.Learn more at: https://brainly.com/question/24372542?referrer=searchResults

What is the importance of global winds moving warm air away from the equator?
Explanation:
Warm air rises, creating a low pressure zone; cool air sinks, creating a high pressure zone.
Air that moves horizontally between high and low pressure zones makes wind. The greater the pressure difference between the pressure zones the faster the wind moves.
Convection in the atmosphere creates the planet’s weather. When warm air rises and cools in a low pressure zone, it may not be able to hold all the water it contains as vapor. Some water vapor may condense to form clouds or precipitation. When cool air descends, it warms. Since it can then hold more moisture, the descending air will evaporate water on the ground.
Air moving between large high and low pressure systems creates the global wind belts that profoundly affect regional climate. Smaller pressure systems create localized winds that affect the weather and climate of a local area.

Which would least likely result from a chromosomal change?
death of the cell or organism

change to the phenotype of the organism
Answer:
The answer is B
Explanation:
Compare and contrast a few aspects of animal and plant cells. You can focus on intra- and extracellular structures they share or don't share, but also be sure to describe processes they both utilize or don't both utilize. Some things to consider: How they obtain 'food' (what is their organic carbon source?) What structures do they share that prokaryotes lack? What do they share that all living cells also share? Do they use CO2, and/or O2 in any processes?
Answer and explanation:
Although they share some similarities because they are both eukaryotes, plant cells and animal cells are quite different from each other, which is logical since they have distinct lives.
For example, animal cells and plant cells both have a cell membrane, but only the plant cells have a cell wall - which is thick and resistant, and this makes sense because they are more exposed to mechanical and osmotic stress.
Since animals can move towards sources of water but plants cannot, there's also a way in which plants store water in the cells: vacuoles. Animal cells have vacuoles as well although they are much smaller than the single huge vacuole that plant cells have.
All living organisms need the energy to sustain different cellular processes. The organelle in charge of the chemical reactions behind the obtention of energy is the mitochondria, which is present in all cells, but the mitochondrion needs a specific substrate: glucose. Glucose is obtained in diverse ways: animals move and find food that contains glucose in it, while plants produce their own glucose with a specific process called photosynthesis, for which they need an organelle called chloroplast, which animals do not have. In order to transform the glucose into energy, the mitochondria end up generating CO2, which animals expel from their bodies by exhaling. This CO2, now in the air, is used by plant cells as a substrate in photosynthesis (which needs sunlight as well) to produce glucose and also O2, that will be inhaled by animals and used by their tissues.
All living organisms have one thing in common: they possess DNA. DNA contains all of the genetic information of an organism, and it is present in almost every cell of that organism -if it happens to be a multicellular being-. While prokaryotes have their DNA condensed into a single circular chromosome, eukaryotes like plants and animals, have their DNA form many linear chromosomes (quantity varies according to the species) and these chromosomes are inside a very specialized organelle: the nucleus, which prokaryotes do not have.
