multicellular organisms have many cells. what is the one other characteristic they must have before they can be called multicellular? a. the cells must be small. b. they must be autotrophs. c. they must be heterotrophs. d. the cells must be specialized.

Answers

Answer 1
Answer:

Answer:

The answer is D. the cells must be specialized.

Explanation:

A multicellular organism is one that is constituted by two or more cells which arise from a single cell which multiplies generating an organism. The cells of multicellular organisms aredifferentiated to perform specialized functions and reproduce by mitosis and meiosis.Cellular specialization includes the division of biochemical functions, the specialization of cells for contact with the environment and the separation between somatic cell and germ cell.

Answer 2
Answer: D. the cells must be speacialised

Which would be an example of a secondary consumer?A. a rabbit
B. a fox
C. a cow
D. a mouse

Answers

Answer:

B. a fox

Explanation:

A secondary consumer is those that, to produce energy, consume primary consumers. Those are always herbivores or organisms that only eat autotrophic plants.

In this case, a rabbit and a cow are primary consumers.

The mouse is herbivores too.

The only option left is Fox.

Foxes eat other animals, they are carnivorous. This made the fox a secondary consumer.

B.a fox is a good example of a secondary consumer.

What would happen if a mutation created a new allele that decreased fitness?

Answers

Fitness describes a reproductive success of an individual. For example, there are green and yellow beetles in a population. If a color affects the reproductive success, for example, green beetles will have more offspring that the brown ones because of their color. So, green beetles have higher fitness. And the beetles with decreased fitness will have less offspring.

So, if a mutation creates a new allele which decreases the fitness, the altered allele will not be inherited in such a ratio as the unaltered allele will.

One parent has curly hair, the other has straight hair, and their child has wavy hair. This is an example ofA. incomplete dominance.
B. polygenic inheritance.
C. codominance.
D. multiple allele traits.

Answers

Answer: The correct answer is- A) Incomplete dominance.

Incomplete dominance means neither of the allele ( that is dominant and recessive allele) shows its phenotype complelety. In other words, no allele is completely dominant and a heterozygous condition produces an intermediate phenotype that lies between a dominant and a recessive trait.

As per the question, the phenotype of parents are - curly hair and straight hair.

As child expresses and intermediate phenotype that is wavy hair, therefore it is an example of incomplete dominance.      

Incomplete dominance

Within eukaryotic cells, there is an intricate network of _______ with unique functions.

Answers

Within eukaryotic cells, there is a network of organelles which have unique functions.
An organelle is termed as a specialized subunit within a cell which has specific functions and their functions are very vital for a cell to live. Organelles can be identified by microscopy and purified by cell fractionation.
 In eukaryotic cells has many types of organelles. Larger organelles which are found in eukaryotic cells are visible with the light microscope, for example, vacuole and nucleus.
Some of the major eukaryotic organelles include plastid, endoplasmic reticulum, flagellum, mitochondrion, vacuole, nucleus and Golgi apparatus

Within eukaryotic cells, there is a network of organelles that have unique functions.

Further Explanation:

An ecosystem is made up of mainly two kinds of cells:

  • Eukaryotes cells: They mainly consist of a group of animals, fungi, and plants.
  • Prokaryotes cells: They mainly consist of bacteria and archaea.

Some main features of eukaryotic cells are:

  • They consist of membrane-bound organelles and nucleus  
  • The DNA of a eukaryotic cell is present inside the nucleus of a cell.
  • The nucleus that is surrounded by a membrane is referred to as a true nucleus.

Specialized sections present inside the eukaryotic cells are called organelles. Different functions are performed by different organelles inside the cell. They are the specialized unit in eukaryotes and play several important functions for a cell to survive. Organelles can easily visualize by a microscope and can isolate by cell fractionation method.

The eukaryotic cell has a different type of organelle and plays a specific function for example  

  • Endoplasmic reticulum: They help in synthesizing protein and lipids.
  • Mitochondrion: It produces energy and is called the powerhouse of the cell.
  • Golgi apparatus: It helps in packaging and modification of a protein.
  • Chloroplast: It helps in photosynthesis.
  • Nucleus: It contains the genetic material of a cell.
  • Vacuole: It contains cell sap.
