Answer: The way a disease would affect a flowering plant is by altering the roots of the plant, by this problem the plant could not get any nutrients from the soil meaning it would stop growing and eventually die.
Answer: Option E. All the statements are correct.
Explanation:
Thyroid gland is an endocrine gland that is found in front of the neck, it consists of two lobes connected by isthimus. It is in front of the neck lying against and around the front of larynx and trachea. Thyroid gland secretes three hormones which are thyroxine, triiodothyronine and calcitonin. Thyroxine and trio doth tribune are thyroid hormone. The parathyroid glands are tiny structures found in the thyroid gland. A thick connective tissue separates the parathyroid glands from thyroid tissues. The thyroid gland is controlled by thyroid stimulating hormone called thyrotropin which is released from the anterior pituitary gland which triggers the release of thyroid hormones.
A punnet square predict the traits of offspring genetic crosses and test crosses.
<u>Explanation:</u>
In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.
The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by genetic crosses.
In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.
Answer:

abiotic factors.
Explanation:
Ecosystems need energy imput, need both consumers and producers, and can exist on land, lakes, rivers and oceans.
Answer:
