Answer: The correct answer for the fill in the blank is External fertilization.
Most of the aquatic animals ( like fish) use external fertilization. Male and female release their sperm and eggs respectively in the free water where they are chemically attracted to each other in order to fuse.
Thus, the development of the embryo takes place outside the body ( in the water) of the mother. This means that mother does not carry the developing offspring in this case.
Answer:
Explanation:
Charles Darwin in the Galapagos. Perhaps our first association with the word "Galapagos" is the name "Darwin." Darwin's visit to the Galapagos Islands had a resounding impact on the formation of his Theory of Natural Selection. ... After surveying the coasts of South America, the ship stopped over in the Galapagos Islands.
Answer: visited and took samples to right about his book
Explanation: hope that helped
Hi Brainiac
Parthenogenesis is a method of repetition in which an egg develops without being fertilized by a sperm.
I hope that's help and please rate my answer :)
b. muscle and fat
c. age
d. gender
Muscle and fat will influencing flexibility is dependent upon individual behaviors. Option B is correct.
Flexibility is the ability of a joint or a group of joints to move through a full range of motion. It is influenced by several factors, including joint structure, muscle and fat, age, and gender. Among these factors, muscle and fat are particularly dependent upon individual behaviors.
Joint Structure: The anatomy of the joint itself, including the type of joint and the arrangement of ligaments and tendons, can influence flexibility. Some individuals may naturally have more flexible joints due to their unique joint structure.
Muscle and Fat: The length, strength, and flexibility of muscles and the amount of fat surrounding the joint area can significantly impact flexibility. Regular physical activity, stretching exercises, and conditioning of muscles can improve flexibility over time.
Age: Flexibility tends to decrease with age. As people age, their connective tissues, such as tendons and ligaments, may become less elastic, reducing joint flexibility. However, regular stretching and exercise can help maintain flexibility as one ages.
Gender: In general, women tend to be more flexible than men. This difference is partly due to physiological factors such as differences in collagen content and joint laxity between genders.
Muscle flexibility is closely related to the elasticity and length of muscles. Regular stretching exercises and activities that promote flexibility, such as yoga, can help improve muscle flexibility. Engaging in physical activities and exercises also helps reduce excess fat around the joints, which can enhance joint mobility and flexibility.
Hence, B. is the correct option.

1.Describe the organism (physical appearance, habitat, function, history, etc.).
2.Draw or find a graphic that represents your organism.
3.Detail the organism's method of reproduction:
asexual or sexual
type of gametes
method of fertilization
advantages and disadvantages of the reproduction type
Explanation:
sexual reproduction: Sexual reproduction is the creation of a new organism by combining the genetic material of two organisms. There are two main processes during sexual reproduction: meiosis, involving the halving of the number of chromosomes, and fertilization, involving the fusion of two gametes and the restoration of the original number of chromosomes.
asexual reproduction: any form of reproduction that involves neither meiosis nor fusion of gametes
The endomembrane system consists of the nuclear envelope, ER, Golgi apparatus, lysosomes, vesicles, and plasma membrane. They collaborate to transport, package, and alter proteins and lipids. Components like mitochondria or chloroplasts are not part of the endomembrane system.
The endomembrane system in eukaryotic cells is composed of the nuclear envelope, the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vesicles, and the plasma membrane. These cellular components work together to perform several functions. Notably, they modify, package, tag, and transport proteins and lipids that form the membranes.
Starting with the nuclear envelope, it protects the contents of the nucleus by separating it from the cytoplasm. The endoplasmic reticulum synthesizes proteins and lipids. Golgi apparatus serves to further modify, sort, and package these proteins and lipids for transportation. lysosomes are involved in breaking down waste materials and cellular debris in the cell. Vesicles transport molecules around the cell. Finally, the plasma membrane controls the movement of substances in and out of the cell.
The endomembrane system does not include organelles like mitochondria or chloroplasts, as their membranes are not part of this system.
