A. to contain more nutrients
B. to contain more organelles
C. to more readily exchange substances across the cell.
D. to have only small substances travel across the cell.

Answers

Answer: C

The higher the surface area to volume ratio they have, the more effective this process can be.

Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of

Answers

Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.

As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked. This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.

Look at the table for energy used in activities. Ella does 2 hours of dancing a week, plays football for 1 hour a week, and goes swimming for 0.5 hours a week. She has a mass of 55kg. How much extra energy will she need a week in order to do these activities?

Answers

Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

Ella, with a mass of 55 kg, does a series of activities in a week.

Let's calculate how much energy she needs for each activity in total.

Dancing

Ellas does 2 hours of dancing a week, which consumes 18 kJ/kg.h.

2 h × 55 kg × 18 kJ/kg.h =  1980 kJ

Football

Ella plays 1 hour of football a week, which consumes 25 kJ/kg.h.

1 h × 55 kg × 25 kJ/kg.h =  1375 kJ

Swimming

Ella goes swimming for 0.5 hours a week, which consumes 20 kJ/kg.h.

0.5 h × 55 kg × 20 kJ/kg.h =  550 kJ

Total energy expenditure

E = 1980 kJ + 1375 kJ + 550 kJ = 3905 kJ

Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

explain the interaction between geological events, human population, and the environment

Answers

The relationship between the environment, human population and geological events is complex and multidimensional. While human activities can also have significant effects on geological processes, geological events such as earthquakes, volcanic eruptions and climate change can have significant effects on the environment and human populations.

What is an Environment?

The conditions and forces that surround an organism, population or community are called its environment. It includes all elements of the Earth, both living and non-living, such as the atmosphere, hydrosphere, lithosphere, and biosphere.

The environment is a complex system that living things interact with and influence how they survive, develop and thrive. This includes biological elements such as plants, animals, microorganisms and their interactions, as well as physical elements such as temperature, light, water, soil, wind and topography.

Therefore, the relationship between the environment, human population and geological events is complex and multidimensional.

Compared to other routes of administration, ________ is the most complicated way for a drug to enter the bloodstream.

Answers

Answer: the answer is oral consumption

Compared to other routes of administration, oral consumption is the most complicated way for a drug to enter the bloodstream.

How many ways can drugs enter the bloodstream?Substances can enter the body in different ways. Drugs can be smoked, inhaled, injected, swallowed (tablets, capsules, liquids), or applied transdermally (applied to the skin). Most of the drugs are taken orally and broken down in the gastrointestinal tract. Once the drug arrives, it is broken down by stomach acid before passing through the liver and into the bloodstream. Medicines can be taken in a variety of ways, including swallowing, inhaling, absorbing through the skin, and injecting. Each method has advantages and disadvantages, and not all methods can be used with all drugs. After the tablet is swallowed, it is usually absorbed through the stomach wall into the blood. These take effect within minutes, but usually take 1-2 hours to reach peak blood levels.

The fern goes through alternation of generations in which there is a Diploid stage and a haploid stage. In the diploid stage under the fern’s leaves there is clusters of sporangium called sorus in which meiosis occurs from the diploids sporocyte creating haploid spores. The haploid spores duplicate through mitosis to turn into a gametophyte. The gametophyte has a upper part which holds the eggs called archegonium and in the lower part where sperm is produced called antheridium.After fertilization occurs the egg duplicates and turns into a zygote and eventually back to a diploid sporophyte firn.

what does it mean for a bacteria or protist to be photosynthetic?

Answers

Answer:

Because we know that photosynthesis is a process that plants use, we can define photosynthetic protists as 'plant-like' protists that get their nutrients by converting sunlight into energy using photosynthesis.

Explanation:

Photosynthetic organisms, also known as photoautotrophs, are organisms that are capable of photosynthesis. Some of these organisms include higher plants, some protists , and bacteria because we know that photosynthesis is a process that plants use, we can define photosynthetic protists as 'plant-like' protists that get their nutrients by converting sunlight into energy using photosynthesis.Protists can be photosynthetic or heterotrophs (organisms that seek outside sources of food in the form of organic material). They also contain chlorophyll, a pigment which absorbs light energy for photosynthesis. Photosynthetic protists are considered plant-like protists.

In humans, freckles are encoded by a dominant allele. A woman is heterozygous for freckles. According to the law of segregation, allele pairs separate during gamete formation and then randomly unite during fertilization. Which of the following would apply to this woman's child?

The child having an equal chance of inheriting the dominant allele or the

recessive allele for freckles from her mother is what applies.

The law of segregation by Mendel states that diploid organisms have a pair

of alleles and are passed to their offspring at random.

The woman being heterozygous means she has the dominant and recessive

allele present. Due to the law of segregation stating the alleles are passed
