DNA is passed down from parents to offspring.

This means that offspring
have _____ traits as their parents.

Fill the blank

A) different

B) opposite

C) identical

D) similar

Answers

Answer:

D) similar

Explanation:

I think the answer is D because...

First of all, A and B definitely can't be the answer since offsprings inherit some traits from both their parents, so their traits can't be different nor opposite compared to their parents.

Now the reason why I believe choice C is incorrect is because if your traits are the exact same as your parents', you would basically be a clone of them. However, that's not how it works.

An offspring is produced from two parents and their DNA is combined to create an offspring that has SIMILAR traits but not IDENTICAL.

Hopefully this helps :D

How do limiting factors that affect all plant and animal populations also help explain the history of the human population? How do they help predict future changes?

Answers

Answer:

The human population is shaped by limiting factors just like any other population. Limiting factors include space, food, water, disease, oxygen, and temperature. Throughout history, we can see how human settlement, population, and growth has developed to make optimal use of the resources that were available to society. Paying attention to which resources are growing scarcer, which factors are becoming more prevalent, and what society is doing to adapt to the natural changes driven by time and populational development can help us predict future changes that humanity will have to fight or adapt to (such as food and fuel scarcity, as well as increasingly common pandemics that occur as the result of direct and indirect human-caused genetic modification of bacteria and viruses).

I have a biology question to ask.....
True or False:
Organisms range in composition from unicellular microorganisms to multicellular organisms.

Just type in A if True and B if false. Thank you!!

Answers

Answer:

A

Explanation:

I think its true.............

Answer:

A (true)

Explanation:

The given statement is true because the definition of an organism is a life form that meets the criteria of a living thing (there are 6 main criteria for it to be considered a living thing )

It responds to the environment.It grows and develops.It produces offspring.It maintains homeostasis.It has complex chemistry.It consists of cells

Number 6 says that it needs to consist of cells, so if thing organism meets all the other criteria and consists of one or more cells, it is considered living.

So, organisms do range in composition from unicellular microorganisms to multicellular organisms.

In a laboratory experiment, a plant receives sunlight and water, but not carbon dioxide. Predict what happens to the plant and construct an explanation for your prediction using what you know about the light-dependent and light-independent reactions.

Answers

Light dependent reactions oxidize water and make ATP and NADH in the process. This part of photosynthesis could continue to Occur in the aforementioned example. However, for the light independent reactions, carbon dioxide is needed as a reactant to make glucose , so the Calvin Cycle will not continue and the plant would die when it runs out of glucose.

A plant that receives sunlight and water but not carbon dioxide will not be able to produce carbohydrates

Photosynthesis

The process whereby light photosynthesized can broadly be divided into 2:

Light-dependent reactionsLight-independent reactions

The products from the light-dependent reactions are used to fix carbon dioxide into glucose in the light-independent reaction.

Thus, without carbon dioxide, the light-dependent reaction will take place normally while the light-independent reaction cannot because the major reactant is lacking.

If cabbage plant has 9 chromosomes in its reproductive cells, then it means that it has 18 chromosomes in its _ cells

Answers

Answer:

If cabbage plant has 9 chromosomes in its reproductive cells, then it means that it has 18 chromosomes in its somatic cells.

If a cabbage plant has 9 chromosomes in its reproductive cells, then it has 18 chromosomes in its somatic cells. Because it is a diploid plant, the reproductive cells (gametes) will have nine chromosomes, while the somatic cells will have double the number.

What is meiosis?

Meiosis is a process by which four haploid daughter cells (n) are formed from a parent cell (2n); these are called gametes. The cell first undergoes prophase I of meiosis I, where the chromosomes condense. Then the cell enters metaphase I, where the homologous chromosomes are separated. After anaphase I, telophase I, and cytokinesis, the cell is divided into two daughter cells, each having a haploid number (n) of chromosomes.

Then two cells enter meiosis II, where each cell further divides into four cells (n) as the duplicate chromosomes are separated. After the meiosis, a total of four haploid cells are formed. The cabbage gamete cell has 9 chromosomes, so the somatic cell has 2 chromosomes, which are 18 each.

Hence, if a cabbage plant has 9 chromosomes in its reproductive cells, then it has 18 chromosomes in its somatic cells.

The introduction of an invasive species do to the competition within an ecosystem B. increases is correct option.

The introduction of an invasive species typically increases competition within an ecosystem. Invasive species are non-native organisms that are introduced to a new environment, often without natural predators or controls. As a result, they can rapidly multiply and compete with native species for resources such as food, water, and habitat.

This increased competition can have negative impacts on native species, potentially leading to reduced populations, altered behaviors, or even extinction in extreme cases.
