The number of birds in each flock is:

Flock X: 30 birds

Flock Y: 30 birds

Flock Z: 30 birds

The text in the image instructs you to:

Divide each flock's total pieces of food by 300, the total number of pieces of food eaten.

This will give you the proportion of food eaten by each flock.

Multiply the food percentage for each flock by the total number of birds (30).

This will give you the number of birds in each flock.

The table in the image shows the following information:

Flock X: 32 pieces of food eaten, representing 100% of the food.

Flock Y: 180 pieces of food eaten, representing 100% of the food.

Flock Z: 88 pieces of food eaten, representing 100% of the food.

Since the food percentage for each flock is already 100%, you don't need to perform any additional calculations.

Therefore, the number of birds in each flock is:

Flock X: 30 birds

Flock Y: 30 birds

Flock Z: 30 birds

The Calvin cycle

chemical reactions that take place in chloroplasts during photosynthesis

Some plants such as cacti can prepare materials for photosynthesis during the night by a temporary carbon fixation and storage process. This is due to having the ability to open the stomata at this time, and conserve water due to cooler temperatures at night in order to tolerate the heat in the day.

Answer:

A

Explanation:

Answer:

D

Explanation:

CGA CT complementary DNA will be GCT GA.

DNA is made up of four bases: adenine (A), thymine (T), guanine (G), and cytosine (C), according to the Watson-Crick base pairing, which is the foundation for the helical structure of double-stranded DNA.

Complementary base pairing is described as the phenomenon in which guanine always forms hydrogen bonds with cytosine and adenine always forms hydrogen bonds with thymine in DNA.

Base pairing of purine and pyrimidine in either GC or AT.

Base pairs are frequently used to determine the size of a single gene within a DNA molecule. The total number of base pairs is equal to the number of nucleotides in one of the strands.

Thus, we can conclude that option B is correct.

Answer:

Option A, microevolution and macroevolution

Explanation:

Scientist have categorized evolution base on the time scale  into following two categories

a) Macroevolution – These are the processes which take a long time to occur such as formation of a new species, extinction of any rare species etc, Also it affects a large mass of population or the entire population

b) Microevolution – In this,  the processes of change take a short time and usually they impact only a certain set of species for a shorter time period.  

Thus, option A is correct.

Answer:

A. Microevolution and Macroevolution

Explanation:

Scientists break evolution down into 2 parts: Micro and Macro evolution.

- Microevolution is evolution in a community, and it is very slow and gradual. For example, wolves overtime evolved into dogs, and over time, mosquitos became resistant to chemicals set out to kill them.

- Macroevolution is the type of evolution that refers to long, large changes in evolution over long periods of time and can lead to the creating of new species. For example, a dinosaur species evolves over time into a bird species.

Answer:

Glycolysis is the process that receives a supply of NAD+ ions from the fermentation.

Explanation:

When cells need energy but there is no oxygen for aerobic respiration than anaerobic respiration takes place.

Glycolysis is a universal process that provides energy in the form of ATP molecules. Glycolysis requires two molecules of NAD+, which are reduced to NADH during glycolysis. Thus, the regeneration of NAD+ is necessary as if NAD+ is absent, glycolysis cannot be able to continue.  

During anaerobic respiration (respiration in the absence of oxygen), fermentation takes place to regenerate NAD+ used in the process of glycolysis.

It is the third option. Reason being is because the first one describes what they do when danger approaches and it doesn't say anything about moving. The second one describes what they do to protect their young from the harsh environment around them; no movements mentioned. The fourth one just says what a penguin does but they can be standing when they do it; no mention of any movements at all.

Hope this helps!! :)

Answer:

A penguin uses sleek, smooth belly feathers to slide on ice

when an animal has a simple structure of only one cell, they get their nutrients  from their environment. when animals have a more complex structure, you and infer that they are multicellular and they have a specialized way of breaking down their food. thus, meaning they can be herbivores, omnivores, or carnivores.

You can look at their anatomical structures to see what structures they use to digest said food. For instance, if you were to look at a skeleton and saw that the animal had strong, flat-topped teeth, one would assume they are plants because those strong molars are needed to chew the tissue of plants.

Answer:

Bacteria resistant to the antibiotics

Explanation:

Overuse of antibiotics has been proven to increase the mutation rates of bacteria population. The increased mutation increase the chances of developing a strain of bacteria that is resistant to the antibiotic. This eventually renders the antibiotic ineffective  hence opening up risk for a health epidemic catastrophe.

The overuse of antibiotics will most likely influence the natural selection of antibiotic-resistant bacteria. These bacteria evolve mechanisms that protect them from the effects of antibiotics, making standard treatments for bacterial infections less effective.

Antibiotics are used to treat bacterial infections by targeting specific parts of bacterial cells, which can lead to the death or inhibition of these cells without harming human cells. However, when antibiotics are overused – in humans or in livestock such as chickens – it can lead to the natural selection of bacteria that have acquired or mutated genes granting them resistance to these drugs. This process is similar to the evolution of pesticide resistance; only the individuals with genes conferring resistance survive and reproduce. Over time, a higher proportion of bacteria in the population can withstand the antibiotics originally designed to kill them. This is a major concern in public health and animal husbandry because it can lead to the spread of antibiotic-resistant infections, which are harder to treat and manage.

1. Two examples of genetic disorders are CYSTIC FIBROSIS AND SICKLE CELL ANEMIA.

CYSTIC FIBROSIS

Cystic fibrosis is typically inherited when a defect occur in the CFTR gene of an individual. The CFTR gene is responsible for production of a protein that regulates the movement of water and salts out of the body cells. This gene does not perform optimally in people who have cystic fibrosis and this leads to the production of thick, sticky mucus and extremely salty sweat. Individuals who have this disease usually inherit two copies of the defective gene, one from the father and the other one from the mother.

2. SICKLE CELL ANEMIA

Sickle cell anemia is a genetic disorder of the blood, which is cause by inheritance of two copies of abnormal hemoglobin from parents. The hemoglobin is responsible for movement of oxygen all through the human circulatory system. The abnormal hemoglobin causes defective red blood cells, which can not move oxygen around efficiently. Thus, individuals with this disease do not usually get enough oxygen in their blood, this leads to fatigue and chronic pains plus several other negative medical conditions.

Explanation:

Though heat benefits the organism in the form of warmth, it does not benefit the environment in any way

a light for example provides light so you can see, but the heat produced as a result has no beneficial purpose

In life processes within all organisms, energy is obtained and utilized, but some is invariably lost to the environment, predominantly as heat energy. This is explained by the second law of thermodynamics, which asserts that all energy transfers or transformations are never fully efficient.

All organisms utilize energy for their metabolic activities, and during this process, some energy is inevitably lost into the environment. The second law of thermodynamics justifies why this energy dissipation happens. This principle underscores that not all energy transfers and transformations are completely efficient; some amount of energy is lost in a form that is typically unusable, mostly as heat energy.

To illustrate, during cellular metabolic reactions, some energy is lost as heat energy because of the conversion and usage of chemical energy in food. This phenomenon is essential for warm-blooded creatures, as the heat energy assists in maintaining our body temperature.

The release of energy into the environment can occur in several ways, such as through work done or as a chemical, but a significant portion is usually lost in the form of heat due to biochemical reactions. Accordingly, with respect to your question, the option 'a. lost to environment I (in) form of heat' would be the most accurate.

In the Arctic marine ecosystem, polar bears play a vital role. With polar bears gone, the ecosystem will be affected negatively and have a bad influence on other organisms.

Polar bears are vital components of the Arctic ecosystem, but they face a severe threat due to global warming.

The melting of sea ice reduces their ability to hunt seals, which are their primary source of food. The white fur of a polar bear is an adaptation that helps them blend in with their snowy environment, allowing them to approach prey undetected, a trait crucial for their survival in the Arctic biome.

Climate impacts like warming oceans are causing the sea ice to break up earlier, which endangers polar bear populations by decreasing their access to food and increasing the likelihood of cubs not reaching adulthood. The loss of polar bears would not only be a tragedy in itself but would also be indicative of the broader ecological imbalances affecting the Arctic region, which could have cascading effects on global biodiversity.

As the ice continues to melt, polar bears are forced to travel longer distances, sometimes resulting in drowning or inland migration in search of sustenance. Their overall population has declined by twenty percent in the past ten years, highlighting the urgency with which we need to address climate change to protect them and their habitat.
