In what ways is packaging an important use of energy and materials

Answers

Answer:

Packaging allows products/goods to be kept inside. The goods alone is what people need or want. Because of this, too much sophisticated packaging wastes energy and materials, so it can produce, distribute, dispose, and recycle it.

Describe why plant cells are rigid

Answers

Because the walls of neighbouring plant cells cemented together to form the intact plant, are generally thicker, stronger, and most important of all, more rigid than the extracellular matrix produced by animal plants. In evolving relatively rigid walls,  which can be up to many micrometers thick. Early plant cells forfeited the ability to crawl about and adopt a sendentary life-style that has exsisted in all present day plants.

Hope this helped.

plant cells are rigid because they have a cell wall unlike animal cells.

Genetics can influence the amount of body fat an individual possesses true or false?

Answers

The statement is true. The amount of body fat can be influenced by Genetics.

Further Explanation:

Genetics is a branch of biology that deals with the intensive study of genes and their relative functions. Genetics generally focus on genes. A gene comprise of deoxyribonucleic acid (DNA) which constitute a form of genetic instruction. Generated instructions are used to make molecules, and also to control response of chemical as regards life. Genes are typically passed or transferred from parent to offspring. That process is termed as inheritance.

For example, a man who happened to have some amount of body fat tends to have children who may be prone to have certain amount of body fat which is as result of an inheritance; and inheritance comes with traits. Other forms of traits that can be passed across from parent to offspring are heights and the level of blood sugar in the human body.

Genetics influence can be traced to the cell structure of human form, as each person has 23 pairs of chromosomes within, each one belonging to both the father and mother of an offspring. Since genes are found on chromosomes, there are two copies of each gene. Often times, genes may contain varying information which may lead to one gene becoming the dominant one.

Final answer:

Genetics can indeed influence the amount of body fat an individual possesses as genes determine various factors affecting fat storage. However, diet and lifestyle also play a significant role.

Explanation:

The statement is true. Genetics can influence the amount of body fat an individual has to a large extent. Our genes contain DNA, and different variations in this DNA can lead to different levels of fat storage. For example, certain genes determine how efficiently your body converts food into energy, how fat is stored, and where on your body it is stored, leading to different levels of body fat in different individuals. However, other factors such as diet and exercise can also play a role in determining body fat levels alongside genetics.

25) when does the synaptonemal complex disappear?; a) late prophase of meiosis i; b) during fertilization or fusion of gametes; c) early anaphase of meiosis i; d) mid-prophase of meiosis ii; e) late metaphase of meiosis ii

Answers

C) early Anaphase of meiosis.

Final answer:

The synaptonemal complex, which forms between homologous chromosomes during meiosis for crossover or recombination, disappears during the late prophase of Meiosis I.

Explanation:

The synaptonemal complex is a protein structure that forms between two homologous chromosomes during meiosis and it plays a crucial role in the crossover or recombination process. This structure disappears during the late prophase of Meiosis I.

In other words, option a) late prophase of meiosis I is the correct answer. The disappearance of the synaptonemal complex signifies the end of the crossing over process and the start of the chromosomes moving apart.

A group of scientists are studying the effects of different fertilizers on the growth of pea plants. They began their study with 10 pea plants. They gave each plant a different type of fertilizer and tracked their growth over a period of 2 months. What’s the independent variable in this experiment?

Answers

The answer is a type of fertilizer.

An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of fertilizer. So, the growth of pea plants is the dependent variable and different type of fertilizer is the independent variable.
