The alternation of generations in the life cycle of a plant includes the diploid and haploid multicellular stages. diploid and haploid are copies of the chromosomes. The spores in the plant is unicellular and when they start dividing through mitosis, it produces identical cells. These identical cells are all haploid. Haploid stages contain one set of chromosome from either of the parent. These identical cells create a multicellular system called the gametophytes. A gametophyte is the haploid multicellular stage in the life cycle of a plant. The gametophyte makes the gametes. These gametes are responsible for sexual fertilization. It takes place when a sperm (male gametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploid zygote. Diploid stages contain one set of chromosome from each parent. This is where the sporophyte comes in. A sporophyte is the diploid multicellular stage in the life cycle of the plant. It now contains the two sets of chromosomes from each parent.
The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.
Answer: Global warming
Explanation:
Global warming can be defined as the phenomenon in which there is an increase in the global temperature of the world.
This is because there is an increase in the carbon dioxide concentration in the environment.
The increase in the overall carbon dioxide absorbs more heat which tends to increase the temperature of earth.
B. consumer price index (CPI)
C. gross domestic product (GDP)
D.unemployment rate
E. deflation
Answer:
GDP (c)
Explanation:
B. Measure how fast the saplings of different kinds of oaks grow.
C. Cut down an adult red oak and count its rings.
Answer:
Th correct answer is "Grow a sapling from seed and measure its growth periodically."
Explanation:
To find the answer to a question about nature, it is best to plan an experiment in which the natural event in question can be directly observed and measured.
Rainforest primates have adaptations for tree living, like rotating shoulder joints, a widely separated big toe, and stereoscopic vision. Woodland/grassland primates might not require these same adaptations due to spending more time on the ground. However, adaptations can vary widely among species.
The adaptations of rainforest primates and woodland/grassland primates differ in response to their respective habitats. Rainforest primates, such as the orangutan, have developed traits like rotating shoulder joints and a widely separated big toe that facilitate climbing and swinging through trees. Their vision is stereoscopic, enabling them to gauge distances accurately which is crucial in dense forest environments.
On the other hand, woodland/grassland primates might not necessarily have these same adaptations as they might spend more time on the ground. While some may also have prehensile tails or exhibit quadrupedal locomotion, it should be noted that these characteristics can vary widely among species, and no one trait can be used to distinguish all woodland/grassland primates from rainforest ones.
