Which statement(s) about body characteristics is (are) true? Select all that apply. Select one or more: a. If an organism has a soft body, it is more likely to form a fossil because minerals can penetrate it more easily. b. A hard shell is not crushed easily and does not decompose quickly. c.

Organisms are naturally antagonistic (hostile). O b. Females must choose among possible mates. c. Males must defend their territories. O d. Organisms typically produce too many offspring, and resources are limited.
Gametes from two plant species combine and produce a haploid zygote, and that zygote develops into a haploid, hybrid plant that is sterile. The hybrid plant is sterile because meiosis cannot occur and the cells do not contain homologous chromosomes. Hence, the correct options are a and c. If an organism has a soft body, it is less likely to be fossilized because the body breaks down before it can be preserved. Competition occurs because organisms typically produce too many offspring, and resources are limited. This means that not all of the offspring will be able to survive and reproduce. As a result, the offspring must compete for resources such as food, water, and mates. Hence, option d is the correct answer.
Gametes from two plant species combine and produce a haploid zygote, and that zygote develops into a haploid, hybrid plant that is sterile. The hybrid plant is sterile because meiosis cannot occur and the cells do not contain homologous chromosomes. Hence, the correct options are a and c.
Mitosis and the plant's ability to grow is not affected by sterility. Sterility, on the other hand, means that the plant cannot produce any reproductive cells (like gametes), making it unable to reproduce. Therefore, option b and option d are incorrect. Additionally, the hybrid plant's sterility is caused by an odd number of chromosomes, which results in the improper separation of chromosomes during meiosis.
Body characteristics affect the likelihood of fossilization. A hard shell is not easily crushed and decomposes slowly, which allows for better fossilization of the organism. As a result, option b is correct and options a and c are incorrect. If an organism has a hard shell, it is more likely to form a fossil.
If an organism has a soft body, it is less likely to be fossilized because the body breaks down before it can be preserved. Competition occurs because organisms typically produce too many offspring, and resources are limited. This means that not all of the offspring will be able to survive and reproduce. As a result, the offspring must compete for resources such as food, water, and mates. Hence, option d is the correct answer.
Females choosing among possible mates or males defending their territories are examples of intraspecific competition, which is a type of competition that occurs within a species. However, the question is asking why competition occurs in general, and the answer is that resources are limited and organisms produce too many offspring. Therefore, options a, b, and c are incorrect.

Biofilms require a conditioning film for attachment. True of False: Water is not required for conditioning films to develop. A. True B. False
The statement "Biofilms require a conditioning film for attachment" is true because a conditioning film is a layer of organic or inorganic material that accumulates on a surface and prepares it for bacterial attachment and subsequent biofilm formation.
This film can be formed by a variety of sources including saliva, mucus, and other organic compounds. Once the conditioning film is established, bacteria can then attach and begin to form a biofilm.
Regarding the statement "Water is not required for conditioning films to develop," the answer is False. Water is essential for conditioning films to form as it allows for the accumulation of organic and inorganic material on the surface. Without water, the surface would remain clean and unable to support the growth of bacteria or the formation of a biofilm.
In summary, conditioning films are necessary for biofilm formation, and water is a crucial component in the development of conditioning films. Therefore, the statement "Water is not required for conditioning films to develop" is false.

Answer:
To calculate the amount of money raised for conservation from the sale of firearms during 2020, we'll follow these steps:
Step 1: Calculate the total revenue generated from firearm sales.
Total revenue = Number of firearms sold * Price per firearm
Total revenue = 19,000,000 * $500
Total revenue = $9,500,000,000
Step 2: Calculate the amount of excise tax collected.
Excise tax = Total revenue * Excise tax rate
Excise tax = $9,500,000,000 * 0.11
Excise tax = $1,045,000,000
Therefore, the amount of money raised for conservation from the sale of firearms during 2020, based on the given information, is $1,045,000,000.
