They have genetic material from two parents is true about sexual reproduction.
What is sexual reproduction?
Sexual reproduction is the process of combining the genetic information of two individuals of the opposite sex to create new organisms. Genetic information is carried on chromosomes within the nuclei of gametes, which are specialized sex cells.
These gametes are called sperm in males and eggs in females. During sexual reproduction, two gametes participate in a fusion process called fertilization to create a fertilized egg.
The fertilized egg is the progenitor cell of the embryonic offspring and receives half of its DNA from each parent. In humans, the fertilized egg contains 46 chromosomes.
Therefore, They have genetic material from two parents is true about sexual reproduction.

global warming.
B
acid rain.
С
ozone depletion
D
indoor air pollution.
Answer: global warming
Explanation:
Global warming is simply referred to as the long-term heating of the surface of the Earth and this is caused by human activities, and also the burning of primarily fossil fuel, which brings about the pumping of carbon dioxide, greenhouse gases and air pollutants into the atmosphere.
The weatherizing of buildings to reduce heat loss and save on fuel costs has led to an increase in global warming.
When food becomes scarce, hundreds to thousands of independently living
single-celled amoebas join to form a multicellular mass that will later reproduce.
Which level of the hierarchy of organization does this mass most
closely represent?
Organ system
Tissue
Organ
Molecule
Answer:
The correct answer is - tissue.
Explanation:
In an unfavorable condition like scarcity of food, individual unicellular organism amoeba makes a formation a multicellular mass by aggregation of the cells that reproduce when conditions become favorable. These aggregation of cells known as slime molds.
These molds are more similar to the tissue structure in the hierarchy of organization of a multicellular organism. The tissue is the organization level that is similar to this mass as it is also formedby the cells joined together to perform a particular function.

How do researchers hope to understand healthy aging by the study of proteins?
Answer:
Of course, you could scan their driver’s license or look for signs of facial wrinkles and gray hair. But, as researchers just found in a new study, you also could get pretty close to the answer by doing a blood test.
Woman looking at herself in mirror That may seem surprising. But in a recent study in Nature Medicine, an NIH-funded research team was able to gauge a person’s age quite reliably by analyzing a blood sample for levels of a few hundred proteins. The results offer important new insights into what happens as we age.
Explanation:
For example, the team suggests that the biological aging process isn’t steady and appears to accelerate periodically — with the greatest bursts coming, on average, around ages 34, 60, and 78
Arteries carry blood away from the heart.
True
False
Answer:
True
Explanation:
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

The
is the point at which environmental resources limit
population growth.
O A. exponential growth
O B. carrying capacity
O C. population crisis
O D. logistic growth
Answer:
Carrying Capacity
Explanation:
The limits due to environmental resources such as food and mates.
The point at which environmental resources limit population growth is known as the carrying capacity. Therefore, the correct answer is B. carrying capacity.
What is Carrying capacity?Carrying capacity refers to the maximum number of individuals of a given species that a particular environment can support sustainably over time, taking into account the available resources, such as food, water, shelter, and space.
When a population exceeds its carrying capacity, it can lead to resource depletion, environmental degradation, and ultimately, a decline in population size.
Logistic growth is a type of population growth that takes into account the carrying capacity of an environment. It starts with exponential growth and then levels off as the population approaches the carrying capacity.
Population crisis is a term that generally refers to a situation in which a population faces significant challenges, such as food scarcity, disease, or conflict, that threaten its survival.

Briefly describe why plants produce flowers.
Answer:
The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

b. The Cnidaria are asymmetrical, while the Porifera are radially symmetrical.
c. Both the Porifera and the Cnidaria are asymmetrical.
d. Both the Porifera and the Cnidaria are radially symmetrical.
Answer:
The correct answer is - a. The Porifera are asymmetrical, while the Cnidaria are radially symmetrical.
Explanation:
In biology, symmetry f the body is meant the presence of a pair of organs in an orderly manner that if divide the body each part is a mirror of the other. In the phylum Porifera have asymmetric body plane.
Some animals develop into adults with radial symmetry. Cnidaria adults have radial symmetry type of body plans that eans if they are cut from the middle they divide in the two equal organs into both sides.

7) Water evaporating from the surface of a lake moves from the?
The water cycle or the hydrological cycle is the motion of water from the surface of the earth into the atmosphere and is cycled into the ecosystem.
Most of the water on the surface of the earth is recycled by the cyclic mechanism of the sun. The processes of evaporation, condensation, and precipitation are responsible for the cyclic motion of the water on earth. The escaping of water molecules due to the wind and or due to rise in temperatures in the lake move above from the surface after attaining low pressure.Thus the vaporized form of water moves away from the lake.
